Background The optimal waveform for internal atrial defibrillation (IAD) in humans is unknown. This study tested the effect of waveform duration and phase duration on the efficacy of biphasic waveforms for IAD. Methods and Results Electrodes were pos

J.B. is a well-trained male with syncope due to paroxysmal AV nodal heart block who ultimately required a permanent pacemaker despite an initial attempt at cessation of training only. Baseline sinus node function was normal, but AV nodal conduction r

Though some biphasic waveforms significantly decrease the energy required for defibrillation, little is known about the effect of biphasic stimulation on the determination of other electrophysiological parameters in normal and infarcted hearts. To ev

Recent experimental results pertinent to the modeling of defibrillation are presented. The extracellular potential gradient created by a large electric stimulus predicts whether or not several different types of electrophysiologic response will occur

The use of cardiac activation mapping to study ventricular fibrillation (VF) is discussed. The locations of isochrones in maps are based on decisions on whether and when segments of the electrogram have local electrical activation. The authors compar

In order to be able to derive some quantitative criteria to assist in making decisions about the presence of local activations, zones of canine myocardium incapable of undergoing electrical activation (EA) were created. The criteria are based on the
