J Cardiac Failure . Radiofrequency ablation of the right atrium reduces atrial defibrillation thresholds and changes fibrillatory activity. Distribution of successful shock energies using a biphasic waveform in a pig model of spontaneous ischemic ventricular fibrillation. Ventricular fibrillation characteristics are different in different species. Organizational changes in atrial fibrillation produced by a single radiofrequency ablation lesion remain local to the lesion site.
Heart failure changes activation patterns during ventricular fibrillation.
Long duration shocks prevent wave front propagation. Different tissue heating effectiveness of phased and non-phased radiofrequency energy during linear ablation. Spontaneous tachyarrhythmias and sudden death in a conscious ovine model of myocardial infarction and complete atrioventricular block. Optimization of relationship between auxiliary and primary shock waveforms in dual shock defibrillation. Detection of regional myocardial ischemia using an ICD lead set.
