Abstract

Ventricular fibrillation (VF) is the primary rhythm associated with cardiac arrest characterized as rapid, disorganized contractions
of the heart with complex electrocardiogram (ECG) patterns. Recent studies have reported that performing cardiopulmonary
resuscitation (CPR) procedure prior to shock increases the survival rate especially especially when VF is untreated
for more than 5 minutes. The waveform analysis is objective help in the choice of the right therapy (shock parameters, shock
first or CPR first, drug administration). This analysis is a precondition of individually optimized defibrillation and contribute
substantially to an increased quality of CPR and reduce delivery of failed rescue shock. Animal and clinical studies confirmed
that ventricular fibrillation waveform analysis contains information to reliably predict the countershock success rate
and further improved countershock outcome prediction.
