Synchronized Cardioversion Using the LIFEPAK 6s

2. Verify the integrity of the ECG patient electrodes and the fidelity of the ECG
waveform for tall, distinct R-waves and minimal artifact.
3. Connect the Propaq Encore end of the Welch Allyn Defib Sync cable to the Propaq’s
right side panel DEFIB SYNCHRO connector.
4. Connect the other end of the cable to the LIFEPAK 6s
SYNC connector at the top rear of the defibrillator.
5. With the LIFEPAK 6s turned on, press the SYNC button
on the front control panel.
The button lights when activated.
6. After the SYNC button has been
activated, check that dashed lines appear
above and below each QRS on the
Propaq Encore display. The LIFEPAK 6s
SYNC button will flash with each QRS.
(See page 133.)
Warning The R-wave amplitude must be at least 0.5 mV (5 mm tall when the
Propaq Encore ECG sensitivity—
SIZE
button—is set to 1 mV/cm) to guarantee
that the defibrillator sync pulse will occur no later than 35 milliseconds after the
peak of an R-wave. Reposition the patient electrodes or change the Propaq’s
lead selection as necessary to ensure sufficient ECG waveform amplitude.
However, make sure the R-wave amplitude is not so high that it obscures the
displayed sync markers.
As a visual gauge for estimating R-wave amplitude, the ‘V’ of the mV/cm label
to the left of the ECG waveform is about 4 mm in height. With the Propaq
Encore ECG sensitivity set to 1 mV/cm, compare the letter ‘V’ with the height
of the R-wave, which should be at least 5 mm tall.
