Performing Synchronized Cardioversion

4
This chapter contains information about performing synchronized cardioversion on
a patient with the CodeMaster XL+ defibrillator/monitor.
Refer to Chapter 3, Monitoring for information on patient preparation.

Performing Cardioversion

4
Treatment for certain arrhythmias require 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, we recommend that you perform
WARNING
synchronized cardioversion procedures while directly monitoring
the patient through the defibrillator's pads or leads inputs. If you
use an external monitor as the ECG source, ask your biomedical
technician to verify that the monitor/CodeMaster XL+
combination will deliver a synchronized shock within 60 ms of the
peak of the R-wave. (See the 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.
When the patient is already connected to bedside monitoring equipment, there is a
cable which plugs into the ECG output jack of the bedside monitor and connects to
the CodeMaster XL+ for monitoring. To use an external monitor with the
CodeMaster XL+, perform the following steps.
