Perform Synchronous Cardioversion
1. Set up the LIFEPAK 5 Defibrillator and any other instrumentation according to institutional
procedures and manufacturer’s operating instructions.
2. Confirm the monitor displays an ECG waveform with tall, distinct R-waves and minimal
artifact.
Warning
The R-wave amplitude must be at least 0.5 mV (5 mm tall when the Propaq CS monitor ECG SIZE 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.
1
Reposition the patient electrodes or change the Propaq CS monitor 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.
3. With the defibrillator turned on, press the defibrillator
SYNC button. Confirm the SYNC button light turns on.
4. Check the monitor display for
synchronization markers as shown.
The markers should be nearly
simultaneous with the R-waves.
Confirm the SYNC button also
flashes with each R-wave.
1. 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 CS monitor 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.
