Performing Synchronized Cardioversion
This chapter contains information about performing synchronized cardioversion on
a patient with the HP CodeMaster 100.
Refer to “Preparing the Patient” on page 5-5 for information on patient preparation.

Performing Cardioversion
Treatment for certain arrhythmias requires synchronizing a defibrillator shock with
the ECG’s R-wave. It is essential that this R-wave is detected to avoid inducing
ventricular fibrillation.
Monitoring During Cardioversion
Using an External Monitor
Whenever possible, Hewlett-Packard recommends that you perform
synchronized cardioversion procedures while directly monitoring the
patient through the multifunction defib electrodes or ECG leads inputs.
If you use an external monitor as the ECG source, ask your biomedical
technician to verify that the CodeMaster 100 defibrillator and external
monitor combination will deliver a synchronized shock within 60 ms of the
peak of the R-wave. (See the
HP M2475B CodeMaster 100 Portable
Defibrillator/Monitor Service Manual for test procedure.) Use a 1 mV QRS
complex with a QRS width of 40 ms. This performance cannot be
guaranteed with all commercially available monitors.
