Quantifying myocardial organization using coherence analysis during ventricular fibrillation and for defibrillation research: a single reference electrode approach


This study investigated local epicardial electrical organization during ventricular fibrillation (VF), and its relationship with defibrillation outcome. Unipolar electrograms (5 seconds duration) prior to defibrillation shock were recorded from 112 epicardial sites during 168 defibrillation attempts on nine canine subjects. Magnitude-squared coherence (MSC… (More)
