Accessing the Analyzer Tests
The Analyzer uses a series of menus to access various
Analyzer functions and setup variables. As shown in
Figure 4, the Analyzer indicates three different defibrillator
tests (Energy, Sync, and Charge Time) along the bottom
of the display. An Exit selection is also indicated as a way
of backing out of the defibrillator tests. Pressing a softkey
(F1 through F5) under a specific test will cause that test to
be selected.

Figure 7. Defibrillator Energy Test
If the waveform characteristics are correct, then charge
the defibrillator using one of the energy settings, and with
the defib paddles on the Analyzer’s input, press the
discharge button. The Analyzer senses the discharge and
the energy delivered appears in the display in Joules.
Changing Waveform Characteristics
If the waveform characteristics are not the desired ones,
press the softkey labeled Set Wave. The waveform, its
amplitude, and frequency are new softkey selections.
Press the softkey under the signal attribute you want to
change. Use G or H to scroll through all the values. Once
the desired value is set, press the softkey under the
adjusted characteristic. This same process applies to
Amplitude and Rate selections as well. With the three
parameters set, press the softkey labeled Done to return
to the discharge ready state.
The softkey labeled Summary provides additional
information about the current discharge waveform
depending on the defibrillator type tested. For dc
Monophasic: peak voltage, peak current and pulse width.
For dc bi-phasic: peak and average voltage, peak and
average current, pulse width, interphase delay, and overall
tilt. For ac bi-phasic: all dc bi-phasic data and ac carrier
base frequency and duty cycle.
Note
AC Pulsed Bi-Phasic waveform has not been
approved in the United States.
Testing Defibrillator Synchronization
From the Defibrillator main menu, press the softkey
labeled Sync. As shown in Figure 8, the waveform
selection is already set.
Figure 8. Defibrillator Synchronization Test
The test measures the response of the defibrillator in its
synchronous (sync) mode. Place the defibrillator in this
mode. The defibrillator will now synchronize its discharge
pulse with the ECG heart rate. The sync time measured is

Defibrillator/Transcutaneous Pacemaker Analyzer
Analyzing Defibrillators
the time from the ECG heart beat ‘R’ wave to the onset of
the defibrillator pulse.
If the waveform characteristics are not correct, then
change the characteristics as explained in the “Changing
Waveform Characteristics” section earlier in this manual.
With the waveform set to the desired characteristics,
charge the defibrillator and discharge it into the Analyzer’s
defibrillator inputs. The Analyzer senses the discharge and
the measured delay appears in the display.
The Analyzer can automatically identify the correct
defibrillator waveforms delivered by the defibrillator under
test. The softkey labeled Summary provides information
about the current discharge waveform depending on the
defibrillator type tested. For dc monophasic: peak voltage,
peak current and pulse width. For dc bi-phasic: peak and
average voltage, peak and average current, pulse width,
interphase delay, and overall tilt. For ac bi-phasic: all dc
bi-phasic data and ac carrier base frequency and duty
cycle.
Testing Defibrillator Charge Time
Before starting the charge time test, ensure the
defibrillator is not charged. This test measures the amount
of time it takes the defibrillator to go from a full discharge
to charge at the desired charge level (typically maximum
setting) and then discharge into the Analyzer’s test load.
From the Defibrillator main menu, press the softkey
labeled Charge Time. As shown in Figure 9, the
waveform selection is already set and Measure Charge
Time… is displayed.
fak06.eps
Figure 9. Defibrillator Charge Time Test
In a few seconds after pressing the softkey labeled
Measure, a Charge Defib in: countdown begins. When
the countdown reaches zero and sounds the beeper,
press the charge button on the defibrillator. The Analyzer
begins a Charge Time count up. When the defibrillator
reaches full charge, discharge the defibrillator into the
Analyzer.
Note
For this test the Analyzer is timing operator
actions. The measurement depends on the user
accurately starting the defibrillator as soon as it is
charged. Any operator time delay is included in
the measurement result. The user should repeat
any tests that have not been timed accurately.

average current, pulse width, interphase delay, and overall
tilt. For ac bi-phasic: all dc bi-phasic data and ac carrier
base frequency and duty cycle.
Analyzing Pacemakers (7000DP only)
The Analyzer is designed to work with a variety of
pacemaker brands. See the specifications section later in
this manual for a list of pacemaker brands. The Analyzer
measures and displays pacemaker pulse amplitude, rate,
and width. It also performs demand sensitivity tests,
measures and displays refractory periods, and tests the
pacemaker’s susceptibility to 50/60 Hz interference.
Setting Up the Analyzer for Pacer Testing
W Caution
To avoid damage to the Analyzer or
defibrillator, do not apply defibrillator pulses
to the pacer inputs.
Connect the pacemaker to be tested to the Analyzer
through either the pacer input jacks or defibrillator jacks as
shown in Figure 11.
For tests where the pacemaker interacts with the
simulated heart beat (Async, Demand, Sensitivity, and
Refractory Period tests), the pacemaker senses the heart
beat on its ECG leads. Connect the ECG leads to the
Analyzer ECG posts as shown in Figure 20.
In preparation for testing a pacemaker, the Analyzer will
have to be set to the specific brand of the pacemaker
under test. Press N to enter the top-level pacer menu
shown in Figure 10.

Users Manual
Press the softkey labeled Brand to activate the brand list
and scroll through the list using G or H. When the correct
brand is displayed, enter the selection in one of three
ways. Press the softkey labeled Brand, press one of the
other two setup function softkeys (Load or Input Jacks)
or press the softkey labeled Done.
The load the pacer is working into through the Analyzer’s
pacer inputs is set through the Load softkey. If the load
value needs to be changed, press the softkey labeled
Load and then use G or H to select a value between 50
and 1500 Ω in 50 Ω steps. Set the load value by pressing
the Load softkey again, press one of the other two pacer
variable softkeys, or press the softkey labeled Done.
Note
The load value is only selectable when the pacer
Ω
input selection is set to input jacks. Only a 50
load is available when the input selection is set to
Defib.
The third pacer variable is the selection of the jacks where
the pacemaker has been attached to the Analyzer. The
input jacks softkey toggles between two settings: Input
Jacks or Defib. The Input Jacks selection monitors the
jack just to the left of the function and setup buttons. When
Defib is selected, the Analyzer monitors the pacemaker
through the defibrillator jacks.
When all three pacer setup variables are set to their
desired values, press the softkey labeled Done. The
Analyzer begins to monitor the pacer signal through the
selected input jacks. When the pacer signal is detected
the display indicates the pacemakers pulse rate, pulse
width, energy, and amplitude. In addition, pacer test
function labels appear above the softkeys indicating the
Analyzer is ready to perform one of the pacer tests. See
Figure 12.

Performing a Pacer Asynchronous Test
This qualitative test verifies the continuous (or nondemand) mode pacemaker’s ability to interact with a
simulated ECG signal. The Analyzer first measures the
pacemaker’s applied pulse rate then computes
“underdrive” and “overdrive” rates for the simulated ECG
signal. Initially, the “underdrive” rate is 85 % of the applied
pacemaker rate and the “overdrive” rate is 115 % of the
applied pacemaker rate.
