INTRODUCTION: Little investigation has been conducted to assess the atrial defibrillation thresholds of electrode configurations using electrodes designed for internal ventricular defibrillation (right ventricle [RV], superior vena cava [SVC], and pu

Background —The standard lead configuration for internal atrial defibrillation consists of a shock between electrodes in the right atrial appendage (RAA) and coronary sinus (CS). We tested the hypothesis that the atrial defibrillation threshold (AD

Background —Although T-wave alternans has been closely associated with vulnerability to ventricular arrhythmias, the cellular processes underlying T-wave alternans and their role, if any, in the mechanism of reentry remain unclear. Methods and Resu

Background —Previously, we have shown that a premature stimulus can significantly modulate spatial gradients of ventricular repolarization (ie, modulated dispersion), which result from heterogeneous electrophysiological properties between cells. Th

Although angiotensin-converting enzyme (ACE) inhibitors are known to influence favorably the structural remodeling of the heart after myocardial infarction, the mechanisms by which ACE inhibitors improve survival are not well understood. The hypothes

INTRODUCTION Regional dispersions of repolarization (DOR) are arrhythmogenic perturbations that are closely associated with reentry. However, the characteristics of DOR have not been well defined or adequately analyzed because previous algorithms did

Recent evidence suggests that ion channels governing the response of action potential duration (APD) to a premature stimulus (ie, APD restitution) are heterogeneously dispersed throughout the heart. However, because of limitations of conventional ele

Background— Biological pacemakers (BPM) implanted in canine left bundle branch function competitively with electronic pacemakers (EPM). We hypothesized that BPM engineered with the use of mE324A mutant murine HCN2 (mHCN2) genes would improve functi

Wavelength Adaptation and Reentry.Introduction: The stability of reentry is thought to depend on a critical balance between the spatial extent of refractory tissue in a reentrant wave (i.e., wavelength λ) and the reentrant path length. Because consi
