A combined method for the detection of ventricular fibrillation

Abstract

This paper proposes a combined algorithm for the detection of ventricular fibrillation and its accwately discriminatr 'on from other rhythms. A total of 95 sinus rhythms, 15 monomorphic ventricular tachycardias, 33 atrial fibrillations, 39 supraventricular tachycardias and 30 ventricular fibrillations were analyzed. The algorithm tests three characteristics of the ventricular fibrillation through the estimation of the isoelectric potential, the power spectrum and the coherence spechum. The algorithm allowed a reliable distinction of ventricular fibrillation fiom the other rhythms. The aim of this algoritbm is to be used in any external device procesSing the d a c e ECG signals.
