INTRODUCTION During ventricular fibrillation (VF), interpretation of a local electrogram and determination of the local activation moment are hampered by remote activity or intervening repolarization waves. Successful defibrillation depends on critical timing of the shock relative to local activation. We tested the applicability of Laplacian electrograms for detection of the moment of local activation during VF. METHODS AND RESULTS From isolated perfused porcine intact hearts, 247 local… CONTINUE READING
