Directions for Use 1

Directions for Use

Intended Use

Caution US Federal law restricts this device to sale by or on the order of a
physician.

The Welch Allyn Holter System is intended to be used as a Holter ambulatory
electrocardiograph system for the purpose of screening for ECG rhythm disturbances up
to a 48-hour period. The Welch Allyn Holter System is intended for use under the
supervision of a physician or those knowledgeable in all aspects of ECG morphology,
rhythm, and arrhythmia.

This procedure is known as a Holter procedure and captures infrequent or activity
provoked ECG rhythm abnormalities outside of the physician’s office.

The Welch Allyn Holter System is comprised of the Welch Allyn Holter Recorder and the
Welch Allyn Holter System Application.

As the patient wears the recorder component of the system, it records ambulatory
electrocardiograph data. The Welch Allyn Holter System Application analyzes the recorder
data.

The Welch Allyn Holter System is not intended for infants weighing less than 10 Kg
(22 lbs).

The Welch Allyn Holter System acquires ambulatory ECG waveforms from patients.
The recorder and associated accessories provide signal acquisition for up to three
channels (HR100 and HR300) or up to eight channels (HR1200) of patient ECG waveforms
through surface electrodes adhered to the body.

The subject devices provide the following diagnostic functions:

• Acquire, view, store, and print ambulatory ECG waveforms from patients.
The recorder and associated accessories provide signal acquisition for up to 12 leads
of patient ECG waveforms through surface electrodes adhered to the patient.

• Using optional Holter algorithms to generate measurements, data presentations and
graphical presentations on an advisory basis for patients. These are presented for
review and interpretation by the clinician based upon knowledge of the patient, the
results of the physical examination, the ambulatory ECG data full disclosure displays,
and other clinical findings.

• Using optional interpretive algorithms to generate measurements, data
presentations, graphical presentations, and interpretive statements on an advisory
basis for patients. These are presented for review and interpretation by the clinician
based upon knowledge of the patient, the results of the physical examination, the
ambulatory ECG data full disclosure displays, and other clinical findings.

2 Directions for Use Welch Allyn Holter System

Indications for Use

WARNING Safety—Computer assisted ECG data acquisition and interpretation
is a valuable tool when used properly. However, no automated interpretation is
completely reliable and a qualified physician shall review the interpretations
before treatment, or non-treatment, of any patient.

The Welch Allyn Holter System is intended for acquiring ambulatory ECG signals from
patients. Patients are people with coronary problems or people with suspected coronary
problems. This ambulatory electrocardiograph, and associated analysis system, can be
used on patients without any limitation on patient age or gender.

The Holter Recorder procedure is one of the many tools that clinicians use to capture
infrequent or activity provoked ECG rhythm abnormalities outside of the physician’s office.
Indications for conducting Holter recording are:

•Arrhythmias

•Chest pain

• Unexplained syncope

• Shortness of breath

• Palpitations

• Evaluation of a pacemaker

• Regulation of anti-arrhythmic drugs

• Evaluation of a patient after myocardial infarction

• Family history of heart disease

Contraindications

Computer assisted ECG data acquisition and interpretation is a valuable tool when used
properly. However, no automated interpretation is completely reliable and interpretations
should be reviewed by a qualified physician before treatment, or non-treatment, of any
patient.

The Welch Allyn Holter System is not intended for infants weighing less than 10 Kg
(22 lbs).

Using optional interpretive algorithms to generate measurements, data presentations,
graphical presentations, and interpretive statements on an advisory basis for patients.

Patient Preparation

Holter Procedure Patient Preparation

When making the appointment, tell the patient:

• Do not remove any electrodes or disconnect lead wires.

• Do not swim, bathe, or shower during the recording period.

• Do wear loose fitting, comfortable clothing to the appointment (shirt-and-pants or
blouse-and-skirt combinations are better than one-piece garments.)

Preparing for Electrode Placement on Patient

WARNING Safety—Leave 5 feet (1.5 meters) of open area around the patient
during recorder hookup and removal.

WARNING Safety—Do not connect external devices to the recorder. Connect
patient lead wires only to the patient electrodes.

WARNING Safety—Keep the recorder and patient cable clean, especially the
components that touch patients.

Caution Verify that dates on applicable accessories have not expired.

14 Directions for Use Welch Allyn Holter System

To Prepare the Patient and Place Electrodes

Caution Always ensure that the appropriate electrode placement is employed

for the lead configuration selected.

Caution ECG electrodes can cause skin irritation. Examine the skin for signs of
irritation or inflammation and avoid placement of the electrode in those areas. If
skin irritation occurs during the procedure advise the patient to remove the
electrodes and contact the health service provider as soon as possible.

Help the patient get comfortable. Patient preparation is important for a successful Holter
procedure.

1. Describe the procedure to the patient.

2. Prepare electrode locations. See Figure 4 on page 15 for 5-lead placement, Figure 5
on page 16 for 7-lead placement, Figure 8 on page 18 for 12-lead placement.

3. Shave the area for electrode placement, if necessary.

4. Clean electrode sites with alcohol.

5. Allow electrode site to dry.

6. Attach the electrodes to the lead wires before attaching to patient.

7. Secure each lead wire. Loop each lead wire into a 1- to 2-inch diameter loop, position
it approximately two inches from each sensor site, and tape it to the skin (see

Figure 3 on page 14). This reduces movements that cause signal artifact.

Figure 3. Patient Lead Wire Stress Loop

Evaluating the Signal Quality from Each Lead

Refer to the Holter System Application Directions for Use.

Clinician tasks

Explain to the patient:

• the recording procedure

• how to record information in the patient diary

• how to use the Patient Event Button

• to avoid contact with water
