6.5 Synchronized Cardioversion
Synchronized Cardioversion allows you to synchronize delivery of the defibrillator shock with the R-wave of the ECG.
To use synchronized cardioversion, press the [>>] and then [Enter Sync] soft keys in the Manual Defib mode. Then “Sync”
appears in the Defibrillation information area and a marker appears above each R-wave, see the figure below:
You can monitor ECG through multifunction electric pads or electrodes connected to a 3-lead ECG cable. Shock is
delivered through pads.
For synchronized cardioversion, we recommend to acquire patient’s ECG through ECG lead set.
6.5.1 Performing Synchronized Cardioversion
1. Connect the pads cable and apply the pads to the patient. If ECG set is used for ECG monitoring, connect the ECG
cable and apply the ECG electrodes to the patient, referring to 7 Monitoring ECG.
2. In Manual Defib mode, press the [>>] and then [Enter Sync] soft keys to activate the synchronous cardioversion
function.
3. Press the [>>] and then [Lead] soft keys to select a lead. The selected lead should have a clear signal and a large
QRS complex.
4. Verify that a white R-wave marker appears above each R-wave. If the R-wave markers do not appear or do not
coincide with the R-waves, for example above the T-waves, select another lead.
5. Verify that the equipment enters the Sync mode, as indicated by the SYNC mark shown in the defibrillation
information area.
6. Press [Energy -] or [Energy +] soft keys to a desired energy level.
7. Press [Charge] soft key to charge.
8. Confirm that a shock is still indicated and that the equipment has charged to the selected energy level. Make sure
no one is touching the patient, bed or any equipment connected to the patient. Call out loudly and clearly, “Stay
Clear!”.
9. Press and hold the Shock button on the equipment. The shock will be delivered when the next R-wave is detected.
