Journal ArticleDOI
Influences of anisotropic tissue structure on reentrant circuits in the epicardial border zone of subacute canine infarcts.
TL;DR: It is proposed that the parallel orientation of the muscle bundles in the epicardial border zone is an important cause of ventricular tachycardia because activation transverse to myocardial fibers is sufficiently slow to permit the occurrence of reentry.
Journal ArticleDOI
Electroanatomic Left Ventricular Mapping in the Porcine Model of Healed Anterior Myocardial Infarction Correlation With Intracardiac Echocardiography and Pathological Analysis
TL;DR: Electroanatomic mapping during sinus rhythm allows accurate 3D characterization of infarct architecture and defines the relationship of electrophysiological and anatomic abnormalities.
Journal ArticleDOI
Optical recordings in the rabbit heart show that defibrillation strength shocks prolong the duration of depolarization and the refractory period.
TL;DR: It is hypothesized that defibrillation threshold-strength shocks were able to elicit a new action potential in already depolarized myocardium by hyperpolarizing portions of the myocardia's cellular membranes and, in so doing, to reactivate the fast sodium current.
Journal ArticleDOI
Conduction block in the inferior vena caval-tricuspid valve isthmus: association with outcome of radiofrequency ablation of type I atrial flutter.
David Schwartzman,David J. Callans,Charles D. Gottlieb,Stephen M. Dillon,Colin Movsowitz,Francis E. Marchlinski +5 more
TL;DR: Isthmus conduction block is associated with flutter ablation success and can occur before achieving persistent block, and follow-up has revealed a low rate of flutter recurrence after achieving isthmus Conduction block, whether the block was achieved in conjunction with termination of flutters.
Journal ArticleDOI
Synchronized repolarization after defibrillation shocks. A possible component of the defibrillation process demonstrated by optical recordings in rabbit heart.
TL;DR: A simple model of reentry is used to illustrate how the constant repolarization response, in addition to wave front termination and refractoriness extension, could play a role in the successful termination of fibrillation by electrical shock.
