Performing Synchronized Cardioversion

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

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 
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.
