SECTION 2

To load paper:

❶ Remove the outer packaging from the paper stack.
❷ Facing the front of the unit, use the release latch on the left side and slide the paper tray cover to the left.
❸ Place the stack of thermal paper into the paper tray such that the grid side of the paper is up when it is pulled

over the paper tray cover. The paper cue mark (a small black rectangle) should be in the lower left corner.

❹ Manually advance one page of paper beyond the closure point of the writer. Make sure the paper lays on

the black roller evenly within the channel of the paper door. If paper is not manually advanced evenly, risk
of jamming or queue faults increases.

➎ Slide writer cover to the right until the cover latches in a locked position. You will hear a sharp click when

the door is properly latched.

NOTE: The paper tray spacer should not be inserted if using standard size paper.

WARNING: Risk of injury to fingers in writer paper door or platen drive mechnisms.

2-2

A4 paper users:

If your ELI 250 was ordered with A4 paper, the paper tray spacer will be inserted in the paper tray and the
configuration option to use A4 paper will be set to YES. If units are purchased with standard paper, the paper
tray spacer will not be provided.

To insert the Paper Tray Spacer:

❶ Slide paper tray spacer towards rear wall of writer tray. Align the bottom four plastic arms with the four

openings in the base of the writer tray. Similarly, align the top 3 plastic arms with the three openings on
the rear wall of the writer tray.

To Apply Power to the Electrocardiograph:

❶ Plug the power cord into an AC wall outlet and into the back of the ELI 250.

(Reference Figure 1-3). Unit powers on automatically and can not be turned off when AC is
connected (unit is in Stand by Mode).

❷ If using battery power, press the power on/off button located on the lower right side of the

keyboard. (Reference Figure 1-5).

Indicators on the Keyboard will Illuminate as Follows:

The AC power indicator illuminates when unit is connected to mains (AC power).

The battery power indicator illuminates when charging and flashes when battery is low (below 11.0 V).
The battery power indicator will turn off when the battery is fully charged.

The electrocardiograph should be connected to AC power for recharging whenever the unit is not in use.

TIP: Battery voltage is displayed at the bottom of Time/Date screen – see below.

NOTE: For typical usage, battery charging time should be approximately 8 hours or less.

CAUTION: When the battery charge is depleted to its lowest level (9.5V), the unit will automatically

power down. To recharge a battery from its lowest level, 30 hours of recharging without operation will
be necessary. Routinely discharging a battery to this level will severely shorten the life of the battery.

Patient Preparation

Correct electrode placement is important for acquiring a successful ECG (see Patient Hookup below).
Consider performing some patient preparation procedures to remove oils, lotions, and hair from the skin.
Optimal skin preparation includes exposing skin on hairy areas, scratching with abrading pad, wiping with
alcohol and a dry gauze pad.

TIP: Electrodes should be stored in an air-tight container. Electrodes will dry out if
not stored properly which will cause loss of adhesion and conductivity.

Flash Size

Flash Size indicates the ECG storage capacity of your electrocardiograph. Normal Flash Size is the standard
memory capacity. If the optional expanded memory has been installed, Expanded will be displayed.

ID Format

This option defines the format for the patient ID information prompts. There are three standard formats:
short, standard, or long. A custom ID format is optional when downloaded from the E-Scribe Data
Management System.

The short format includes the patient's last name and first name, patient ID number, date of birth, which will
automatically calculate the age, and gender field.

The standard format includes the patient's last name, patient ID number, age, height, weight, gender, race,
medication 1, medication 2, and a location field.

The long format is identical to the standard format except that it includes the patient's first name, room and
comment fields.

The custom format, which is designed in the Mortara E-Scribe Data Management System, can be downloaded
to the ELI 250. The custom ID format is uniquely designed to meet your facility’s needs. Please see Appendix
A to download a Custom ID.

SECTION 3

3-8

Auto-Fill ID

When enabled, the system will automatically populate the demographic fields in the ID screen. When the
patient ID field is manually populated and followed either by selecting enter or F2 (▼) the system
automatically scans the patient directory and if records with the exact ID are found, the existing data is used to
fill some of the demographic fields. The auto-fill feature is designed to only automatically populate last name,
first name, date of birth, age and gender. If no matching records are found, a brief message is displayed and
the user must manually enter the patient’s demographics.

NOTE: In order to avoid the use of incorrect data, the Auto-Fill ID feature is only supported if
the ID formats are the same between records and if the records belong to the same site.

AC Filter

The ELI 250 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your
country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that
the proper AC filter is selected.

Paper Speed

The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm
printouts and display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for
display or rhythm printing.

Filter

The ECG plot frequency filter (or print filter) can be set to 40Hz, 150Hz, or 300Hz. The plot frequency
filter does not filter the acquired digital record. A 40Hz plot filter setting will reduce the noise (40Hz and
higher frequencies) on the printed ECG, a 150Hz plot filter setting will reduce the noise (150Hz and
higher frequencies) on the printout and a 300Hz plot filter setting will not filter the printed ECG.

Height/Weight Units

This option defines the units of weight and height to either pounds/inches (lb/in) or kilograms/centimeters (kg/cm).

Date Format

This option defines the format for entering and displaying the patient’s date of birth in either the U.S. format
or the European format.

For example: July 16th, 2003 is displayed as follows:

US Date Format: MM/DD/YYYY (07/16/2003)
European Date Format: DD.MM.YYYY (16.07.2003)

NOTE: the date format option does not modify the acquisition date printed on each ECG.
Using the example above, the acquisition date would print as 16-Jul-2003.

SECTION 3

3-9

Interpretation Option

The ELI 250 automatically analyzes ECGs and prints the optional interpretation on the ECG printout. This
option allows you to select or suppress the “interpretive” text on the ECG report.

NOTE: A qualified physician should review the computer generated ECG interpretation
before the treatment of any patient.

Reasons

The reason statements indicate why a particular interpretive statement was printed. Reason statements
print in [square brackets] within the interpretive text (if the interpretation is turned on). Turning the
reason statement function on or off does not affect the measurements performed or the interpretive
statements selected by the analysis program.

For Example:

Anteroseptal Infarct [40+ MS Q WAVE IN V1-V4]
Where “Anteroseptal Infarct” is the interpretive statement.
And “40+ MS Q WAVE IN V1-V4” is the reason statement or
explanation as to why the interpretive statement was printed.

Configuration Page 3

Append

A status or statement phrase can be appended to the ECG and printed under the interpretive text printout.
Either “unconfirmed report” or “reviewed by” can be selected. However, if you wish to have nothing appended
to the ECG, “blank” may be selected.

Number of Copies

This option defines the number of printed copies when an ECG is taken. A zero (0) setting prints the original
only; one (1) prints the original plus 1 copy; two (2) prints the original plus 2 copies, and so on. Up to 9 copies
may be selected.

SECTION 3

3-10

ECGs Retrieved

This option defines the number of ECGs retrieved from an E-Scribe data management system. The ECGs are
retrieved by ID number. A zero (0) setting retrieves the most current ECG for that ID number. Settings from
one (1) to nine (9) retrieve the most current ECG plus “X” number of ECGs identified by the entered value.
EXAMPLE: If you enter the number 5, you will retrieve the most current ECG plus the five preceding ECGs
for that ID number. ECGs retrieved from the E-Scribe are only printed at the ELI250 and not saved.

Delete Rule

This option defines the ECG auto delete status in the patient directory. ECGs that are marked for deletion
will be automatically removed or erased based on its date (a first in/first out philosophy) to make room
necessary for the new ECG record. ECGs are only erased from the directory when they are marked for
deletion and if the directory becomes full. More than one ECG may be removed from the directory in
order to make room for the the new incoming record. The delete rule selections are:

•Post Plot = ECG is automatically marked deleted after printing

•Post Transmit = ECG is automatically marked deleted after transmission

•Post Plot/Transmit = ECG is automatically marked deleted after transmission and printing

Storage Sensitivity

The ECG storage sensitivity setting dictates the resolution of the stored record. The sensitivity settings are
either Normal or High. If the configuration value is set to High, the stored ECG will have a high resolution.
As a result, the records size will be large and will reduce the storage capacity in the ECG directory.

Auto Save ECG

This option defines whether or not the ELI 250 is to automatically save newly acquired ECGs in the directory,
once they are acquired and printed. If the auto save configuration option is set to NO, and the record is printed,
the ELI 250 will prompt you to “Save ECG?” Save (F1) will store the ECG in the directory.

NOTE: Manually save ECGs by selecting More (F5) from the Acquired ECG
view and Save (F5).

Auto Print ECG

This option defines whether or not the ELI 250 will automatically print the ECG after acquisition. If the
selected configuration option is set to NO, a manual printout is possible after acquisition.

Baud Rate

The user-selectable baud rate determines the serial port’s data transmission rate in bits per second (bps).
Set the baud rate to: 9600, 19200, 38400, 57600, or 115200 bps for direct data transmission between the
ELI 250 and another Mortara cardiograph, and 38400 bps for a direct connection to the E-SCRIBE data
management system.

SECTION 3

Patient Demographics

You may enter patient demographic information before acquisition. The entered patient ID fields will remain
populated until you acquire the ECG. However, when you disconnect the leads from the patient, turn off the
cardiograph, or change a configuration setting before acquisition, the entered patient demographic information
will be cleared for you to enter the demographics of your next patient.

To access the patient demographic data entry menu, press ID (F1) from the Real-Time ECG View. The patient
demographic labels available are determined by the ID format selected in the configuration settings. The short
ID format is pictured below:

NOTE: If a Custom ID has been downloaded to the ELI 250, Custom demographic labels
will appear as it was designed in your E-Scribe data management system. See Appendix A
for more details.

Patient demographic entry can be completed manually for a new patient or automatically from an existing

patient record in the directory. Manually enter the patient demographics and use Enter, Ta b or F1 (▲) and
F2 (▼)to move to each data entry field. Skipped fields will appear as a blank field on the header of the

ECG printout.

TIP: Type the letter F to change the gender to female or type the letter M to change the
gender to male.

To automatically populate the demographics of an existing patient, select the desired patient from the directory
by selecting Direc (F5) from the ID screen.

If the Auto-Fill ID is enabled in the configuration, the system will automatically populate the demographic
fields in the ID screen. When the patient ID field is manually populated and followed either by selecting

enter or F2 (▼) the system automatically scans the patient directory and if records with the exact ID are

found, the existing data is used to fill some of the demographic fields. The auto-fill feature is designed to
only automatically populate last name, first name, date of birth, age and gender. If no matching records are
found, a brief message is displayed and the user must manually enter the patient’s demographics.

NOTE: In order to avoid the use of incorrect data, the Auto-Fill ID feature is only possible
when the ID formats are the same between records.

When time is of the essence or if patient demographics are not available, ID information can be added to
the ECG after it has been acquired via the patient directory. Acquiring an emergency or unidentified ECG
is explained below.

In addition to the Short, Standard or Long patient ID format, the ELI 250 also supports a Custom ID format.
The custom format, which is designed in the E-Scribe data management system, can be downloaded to the

ECG Acquisition, Printing, Storage

Acquisition

When a patient is connected to the electrocardiograph, the ELI 250 is continuously collecting and
processing the ECG data; therefore, you should first instruct the patient to relax in a recumbent position
to ensure that the ECG is free from noise and artifact due to patient activity before you press the Auto
ECG or Auto RHY key.

To acquire an emergency ECG or unidentified ECG for a new patient press the Auto ECG key . The
Real-Time ECG View is replaced with the patient ID menu. Select Enter or Done (F6) and the ECG is
acquired. “Collecting 10 seconds of data” is displayed on the top of the LCD and “captured, analyzed,
formatted” is displayed on the bottom of the LCD. The Real-Time ECG View is then replaced with the
Acquired ECG View. To add patient demographics, select the record from the directory and select ID (F1).

When workflow permits patient demographic entry prior to acquisition, connect the patient to the ELI 250
and enter the patient identification information as explained above. After you complete the last data entry
field select Done (F6) to return to the Real-Time ECG View.

Examine the display for artifact (noise), or baseline drift. Re-prep and replace electrodes if necessary to obtain
satisfactory waveforms. (See Patient Preparation, in Section 2). If a lead fail condition exists square waves
appear on the display for that lead and the lead in fault displays in the upper-left corner of the screen (one
at a time). This is to alert the operator of a lead fail condition. When the problem is corrected, the ELI 250
waits for 10 seconds of good data before analyzing the ECG. Please refer to the following troubleshooting
guide based on Einthoven’s Triangle:

NOTE: New softkey labels are available in the Acquired ECG View.

NOTE: Functions are not available during acquisition.

Printing

If the auto-print configuration option is enabled, an ECG is printed following acquisition. Regardless of
the auto-print configuration setting, a manual printout is possible from the Acquired ECG View by
selecting Print (F4).

Toggle through the available Acquired ECG View waveform formats by selecting Leads (F2). A preview of
the full 10-seconds of ECG waveform is available. The first 5 seconds of waveforms are displayed (page 1 / 2 is
displayed in the upper right corner) and by selecting Page (F3), the last 5 seconds of waveform are displayed
(page 2 / 2 is displayed in the upper right corner). If the auto-print configuration option is disabled, the
10-second preview assists in ensuring a quality ECG acquisition prior to printing. When you acquire an ECG,
the cardiograph captures the previous 10 seconds. The relationship between the display and the printout is the
same – what is displayed in the ECG Acquisition View is what will be printed.

Storage

The ELI 250 manages storage in one of two ways – automatically or manually. When the Auto Save
configuration option is enabled, ECGs are automatically saved upon acquisition and printing. However,
when the Auto Save configuration option is disabled, upon completion of acquisition, a prompt is
presented as follows and saving the ECG record is at the user’s discretion.

NOTE: If Auto Save is enabled, but the ECG is not printed, the user is prompted to save.

TIP: Manual Save is possible by selecting More (F5) and Save (F5) in the Acquired

ECG View.

Acquiring Rhythm Strips

Rhythm strips are printed in the format defined in the configuration (3-channel, 6-channel, or 12-channel).
See section 3 for instructions to configure rhythm leads.

Begin routine rhythm strips by connecting the patient to the ELI 250 and entering the patient identification
information as described in this section. After the last data entry field from the ID menu is completed,
select Done (F6) to return to the Real-Time ECG View. Select the RHY key to begin rhythm printing.

NOTE: Rhythm printouts are only possible from the Real-Time ECG View.

NOTE: Rhythm acquisitions are only printed and not stored in the electrocardiograph.

In addition to manipulating SPEED, GAIN, FILTER during rhythm printing, the user may also toggle different
lead groups. When the default rhythm format is set to either 3-channel or 6-channel, you may change lead
groups during printing by selecting LEADS (F2). The change in lead groups is apparent on the printout whereas
the waveform display will remain in the default display of 2.5 seconds of leads I, II and V1-V6.

During 3-channel rhythm printing, the available lead groups are:

1. Default (user-selected in configuration)

2. I-II-III

3. aVR, aVL, aVF

4. V1-V2-V3

5. V4-V5-V6

During 6-channel rhythm printing, the available lead groups are:

1. Default (user-selected in configuration)

2. I-II-III-aVR-aVL-aVF

3. V1-V2-V3-V4-V5-V6

During 12-channel rhythm printing, switching lead groups is not available.

During rhythm printing, you may place the writer in standby mode, STBY (F6). To continue rhythm printing

Patient Directory

The standard patient directory saves up to 60 ECGs depending on the storage space required for individual
record. The optional expanded memory permits up to 150 ECGs. The heart rate, storage sensitivity, and signal
quality determine the ECG file size and ultimately how much memory is needed to store each record.

To access the directory of stored ECGs, select number 1 from the Application menu and the patient directory
list is displayed.

Application Menu Patient Directory

(sorted by name)

NOTE: In the patient directory list, “P” represents the record has been printed, “X” represents
the record has a delete status, and “T” represents the record has been transmitted.

Management of the ECG record is performed within the directory of stored ECGs. The desired record must
be highlighted in order to view, print, edit or add demographics, and to change delete status.

Use ▼/▲ (F1) to navigate down the directory list and Shift ▼/▲ (F1) to move up the list. Similarly, use
▼▼/▲▲ (F2) to page down and Shift ▼▼/▲▲ (F2) to page up through the directory. To quickly find and

select a patient name, use the keyboard to enter the first letter(s) of the last name. The letters will be
displayed on the lower left corner of the LCD and the desired name will automatically be highlighted.

An ECG may be listed in the directory but have a “deleted status” (indicated by “X”). The directory saves
those records that have been marked for deletion in the event that you may want to recover the ECG at a
later time. All stored ECGs will remain in the directory until it becomes full, at this time, the ELI 250 will
automatically remove a record, based on its size, in order to make room for the new ECG. Only those records
that have been marked for deletion will be removed. Records are automatically marked for deletion based on
the Delete Rule in the configuration. To manually mark an ECG record for deletion, press Delet (F4) and an
“X” will appear. To remove the delete status, select F4 again.

NOTE: Only when the directory becomes full, ECGs that are marked for deletion are
automatically removed from the directory based on their record size to make room
necessary for the new ECG record.

TIP: Use the delete rule in the configuration settings to automatically define the ECG delete
status. (See section 3).

NOTE: Record status symbols: X =deleted, P = printed, T=transmitted. When the directory
is sorted by ID and Date status symbols are displayed on the top row of the LCD. If sorted
by Name, symbols are displayed on the right hand column as pictured below.

E-Scribe workstation. Also, it is required that your IT Manager set the ELI 250 WLAN configuration values.
Refer to section 3 for more information on WLAN configuration setup. The ELI 250 can be configured for
DHCP (Dynamic Host Communication Protocol) and for WEP (Wired Equivalent Privacy) security.

NOTE: Environmental conditions may affect the reliability of WLAN transmissions.

If DHCP is set to NO, your wireless access point will have a static network setting and the following
parameters must be configured in the ELI 250:
IP Address
Def Gateway
Sub Net Mask

If DHCP is set to YES, your wireless access point will have an automatic network setting and IP Address,
Def Gateway and Sub Net Mask do not need to be configured.

In either DHCP setting, the following wireless network parameters must be configured in the ELI 250 by your
IT Manager:
Host IP
Port Number
SSID
Channel Number

NOTE: Addresses are always entered as 4 sets of 3 digits; therefore, an address of 192.168.0.7
must be entered on the ELI 250 as 192.168.000.007.

If WEP Security is disabled on your access point then set Security (WEP) to NO. If WEP Security is enabled
on your access point then the following wireless network parameters must be configured in the ELI 250 by the
IT Manager:
Security (WEP): YES

Requests Download

The ELI 250 can download and process a patient request list from the E-Scribe, which identifies the ECGs
(or ECG orders) needed for particular patients. Request Codes are designed in your E-Scribe Data
Management System, which contain the particular patients who require ECGs. The technician at the cardiograph
selects the desired Request Code (e.g. a code specific to a department or floor) and does not have to enter the
demographic information for the patients belonging to the Request Code. Once downloaded, the patient list
for each Request Code is stored in the cardiograph as the Request List (similar to the patient directory). As
with the other forms of ECG data transmission, you can use either the optional modem or a direct connection.
Follow the hookup instructions under Transmitting Records in this section.

NOTE: A Custom ID must be downloaded before downloading the Requests (please
reference the E-Scribe Operator Manual and Custom ID Format of this Section).

Custom ID Download

Custom ID formats are uniquely defined by your facility’s needs. This customized ECG header information
is designed in the Mortara E-Scribe data management system and downloaded to the ELI 250 as the Group
Name either by serial connection (direct) or modem transmission.

Select Custom ID Download (7) from the Application menu and the following screen appears:

Transmission Status

APPENDIX A

A-19

“Transmission Status” will remain visible for approximately 10 seconds before the following screen appears:

“Waiting for Response”, “Connected”, and “Custom ID downloaded” will be displayed before returning to the
Real-Time ECG View, which indicates the Custom ID download is complete. The new Custom ID becomes
the customized header format for all future ECGs until you select a different ID format in the configuration
settings. You may alter the ID format configuration to Short, Standard, Long or Custom based on your patient
demographic entry needs. The Custom ID is only deleted upon downloading a new Custom ID or on the rare
occasion of downloading software – it will not be lost due to power loss or switching to a different ID format.

TIP: Upon Custom ID download, the ID format will assume the group name as designed in
the E-Scribe.

NOTE: A Custom ID must be downloaded before downloading the Request Codes
(please reference the E-Scribe Operator Manual).

NOTE: The site number must be configured in the cardiograph and recognized as an
established, valid site number at the E-Scribe before downloading the custom ID.

TIP: Confirm the baud rate in the configuration settings before downloading the custom ID
from the E-Scribe.

Inspection and Cleaning

If the hospital or institution fails to implement a satisfactory cleaning and inspection schedule for this
equipment, it may result in equipment failure and health hazards.

NOTE: Only qualified service personnel should repair or replace ELI 250 parts.

Inspecting the ELI 250

Inspect the equipment for the following conditions on a regular basis:

• Examine patient cable, power cable and other accessory cables for obvious damage
(e.g. torn insulation, broken connectors, etc.). Replace cables as necessary.

• No bent prongs or pins on the plugs and connectors. Check the fit of cables with connectors
on the ELI 250 to ensure proper fit.

• All cords and connectors are securely seated in their corresponding connections.

• Examine the equipment for missing screws, cracks or broken areas that might allow unintended
access to internal electronics areas.

Cleaning the ELI 250

Disconnect the power source. Clean the exterior surface of the unit with a damp cloth using a solution of mild
dishwashing detergent diluted in water. After washing, thoroughly dry off the unit with a clean, soft cloth or
paper towel.

Cleaning Print-Head

NOTE: Do not let soap or water come into contact with the writer, plugs, jacks or vents.

Test Operation

After cleaning and inspecting the ELI 250 proper operation of the unit may be confirmed by using an ECG
simulator to acquire and print a standard 12-lead ECG of known amplitude. Printing should be dark and
even across the page. There should be no evidence of print-head dot failure (e.g. breaks in printing forming
horizontal streaks). Paper motion should be smooth and consistent during printing. Waveforms should appear
normal, with proper amplitude, and without distortion or excessive noise. Paper should stop with perforations
near the tear-bar (indicating proper cue sensor operation).

Recommendations to Biomedical Staff

Following any service to the ELI 250 or when non-compliant operation is suspected, Mortara Instrument, Inc.
recommends the following procedures:

• Confirm proper operation

• Perform testing to ensure continued electrical safety of the device
(use IEC 60601-1 or ANSI/AAMI ES1 methods and limits)

• Patient leakage current

• Chassis leakage current

• Earth leakage current

• Dielectric strength (mains and patient circuits)

Cleaning the Patient Cable

Patient cables should be kept clean using a damp cloth of lukewarm soapy water or a neutral cleaner. To
disinfect the patient cable, use a damp cloth of chemical disinfectants containing ethanol (70% - 80%),
propanol (70% - 80%) or aldehydes (2% - 4%).

WARNING: Do not attempt to clean/disinfect the ELI 250 or patient cable(s) by submerging
into a liquid, autoclaving, or steam cleaning. Never expose cables to strong ultra-violet radiation.

Battery Maintenance

The ELI 250 houses an internal sealed lead-acid battery. When installed, the battery has a shelf life
of approximately six months, without recharging. If the battery has been stored for a long period in a
discharged state; it may not be able to regain its capacity even if it is recharged.

For information about replacing the battery, please refer to the ELI 250 service manual.

Mortara Instrument, Inc. recommends that the ELI 250 be plugged into AC power whenever possible to
maximize battery life and for the user to develop a habit of recharging the battery before the unit indicates
“low battery” condition. (That is, reduce depth of discharge.) Battery life varies by how the battery is
maintained and how much it is used. For improved battery life, keep the cardiograph plugged in when not
in use.

The sealed lead-acid battery will provide optimum life when the unit is fully charged after each use. The
ELI 250 will charge a depleted battery to 90% of its capacity in approximately 8 hours or less. To recharge
a battery from its lowest level, 30 hours of recharging without operation will be necessary.

TERM DEFINITION

Augmented lead (aVL, aVR, aVF) The difference between one site and the average

of the potential of two other sites; unipolar extremity leads.

Baseline drift The QRS complexes are present, but the baseline wanders due to

poor skin/electrode contact and/or patient movement.

Bradycardia A slow heart rate.

Calibration pulse Standardization pulse. A base to compare the relationship of QRS

complexes to one another.

Gain An increase in amount, magnitude or degree.

J point The end of the QRS complex; the point where the QRS ends and

the ST segment begins (QRS offset).

Limb lead Bipolar lead that represents the differences of electrical potential

between two selected sites (leads I, II, III).

Muscle noise Grossly uneven baseline caused by patient body tremor or other

muscle movement. The artifact may be so large that it overtakes
the complex.

Precordial leads (V1-V6) Unipolar chest leads.

Premature atrial complex (PAC) An arrhythmia that has its origin in the atrium.

Premature Ventricular Complex (PVC) An arrhythmia that has its origin in the ventricle.

ST depression The amount of ST deviation below the baseline.

ST elevation The amount of ST deviation above the baseline.

ST level The numerical value of the measured ST segment in microvolts.

ST segment Ventricular repolarization. The end of the S wave (J point) to the

beginning of the T wave.

Tachycardia A rapid heart rate.
