CHAPTER 5SYNCHRONIZED CARDIOVERSION

Verify that markers are clearly visible on the monitor and their location is appropriate and
consistent from beat to beat. If necessary, use the LEAD and SIZE buttons to establish settings
that yield the most consistent Sync marker pattern.
The Sync On/Off softkey may be highlighted for clearer visibility, if desired. This is off by
default. Refer to the R Series Configuration Guide for instructions on how to turn on the
highlighting.
The synchronized cardioversion procedure for ZOLL hands-free therapy electrodes is identical
to that for paddles with the exception of the SHOCK button location.
The R Series defibrillator supports two types of synchronized cardioversion:
• Synchronized Cardioversion — The R Series monitors the patient’s ECG and
synchronizes shock delivery with this ECG source. For instructions, refer to “Synchronized
Cardioversion Procedure” below.
• Remote Synchronized Cardioversion — An external device (such as a patient monitor)
monitors the patient’s ECG and provides a synchronization pulse to the R Series’ Sync
In/Marker Out connector. The R Series synchronizes shock delivery with these external
pulses.
Note: When using the Remote Sync function, the procedure and displayed information are
different. Make sure to follow the instructions for Remote Synchronized Cardioversion
on page 5-5.
Synchronized Cardioversion Procedure
Determine the Patient’s Condition and Provide Care Following Local
Medical Protocols
Prepare Patient
Remove all clothing covering the patient’s chest. Dry chest if necessary. If the patient has
excessive chest hair, clip or shave it to ensure proper adhesion of the electrodes.
Attach ECG electrodes as described in“Monitoring Electrodes Attachment” on page 9-3.
A standard ECG cable and ECG electrodes are recommended for use during cardioversion.
Hands-free therapy electrodes may be used as an ECG source. Signal quality will be equal to
that of standard leads except immediately following a discharge when there may be more noise
due to muscle tremors, especially if an electrode is not in complete contact with the skin.
