5.4.3 Function of the Synchronized Defibrillation Procedure
Fig. 5.6 Synchronised defibrillation
For synchronised defibrillation, the defibrillation shock is delivered in synchronisation
with the heart action, as the heart is still working. As a prerequisite, the patient's ECG
signal must be supplied to the defibrillator. After the physician has triggered the
defibrillation shock, the trigger signal for the actual shock delivery will be derived from
the subsequent QRS complex 25 ms after the trigger mark on the monitor screen (1).
In case of absence of QRS, an internal discharge will occur in a delay of 20 – 30
seconds.
 Be aware that after initiation of the shock, the actual shock will be released with
the next trigger signal (QRS) derived from the ECG. This may lead in a shock
delivery delay time of 30 second.
