Synchronized Cardioversion of Atrial Fibrillation

Cardioversion of atrial fibrillation (AF) and overall clinical effectiveness is enhanced by proper
pad placement. Clinical studies (refer to above) of the ZOLL M2 Biphasic Defibrillator
Waveform demonstrated that high conversion rates are achieved when defibrillation pads are
placed as shown in the following diagram.
Back/
Posterior
Place the front (apex) pad on the third intercostal space, mid clavicular line on the right anterior
chest. The back/posterior pad should be placed in the standard posterior position on the
patient's left as shown.

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 (see Chapter 6, "Monitoring ECG" for instructions on attaching ECG
electrodes to the patient).
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 limb/chest 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.
Attach hands-free therapy electrodes according to instructions on the electrode packaging and
as described in "Therapy Electrode Application" on page 9-8.
Ensure that the therapy electrodes are making good contact with the patient's skin and are not
covering any part of any other electrodes.
