Objective: The objective of this study was to investigate the relationship between acute decreases in right ventricular volume during Valsalva strain (with resultant changes in autonomic neural tone) and measures of local endocardial repolarization t

Morning peaks in the circadian variation of sustained ventricular tachycardia (VT) may reflect the contribution of sympathetic activation to onset of VT. We hypothesized that adrenergic blockade would eliminate this morning peak. Fifty-four patients

Adverse ventricular-ventricular interactions have been recognized in those with repaired tetralogy of Fallot (TOF) and severe pulmonary regurgitation.We aimed to examine the impact of pulmonary valve replacement (PVR) on the left heart late after TOF

Background: We had recently established a model for the study of VF in humans using an optical mapping technique in Langendorff perfused human hearts. The optical mapping technique allows for the unequivocal evaluation of wavefront identification, th

Introduction: The most significant change to the latest AHA CPR guidelines is the recommendation of CPR first followed by defibrillation, for un-witnessed arrests. We tested the hypothesis that global myocardial ischemia during ventricular fibrillati

Background Inappropriate therapy from supraventricular tachyarrhythmias (atrial fibrillation [AF] and sinus tachycardia [ST]) in patients with implanted cardioverter defibrillators is a major challenge. We tested the performance of stability algorith
