Flecainide-induced arrhythmia in canine ventricular epicardium. Phase 2 reentry?
BACKGROUND We recently reported that sodium channel block can produce opposite effects on action potential duration (APD) and refractoriness in epicardial versus endocardial tissues of the canine ventricle. In addition, strong sodium channel current inhibition was found to cause loss of the action potential dome in epicardium but not endocardium, thus inducing a marked dispersion of repolarizat...
متن کاملDiscordant S-T alternans contributes to formation of reentry: a possible mechanism of reperfusion arrhythmia.
Although a relationship between S-T alternans and life-threatening arrhythmia has been recognized, the mechanism is poorly understood. We examine the role of S-T alternans in the occurrence of ventricular fibrillation (VF) after reperfusion. The left anterior descending coronary artery was occluded for 20 min and then abruptly reperfused in 12 intravenously anesthetized open-chest dogs. Sixty u...

متن کاملThe Basics and Functions of Putinism in Russia
Abstract:The present Russian political system is tied up with Putin's name; and Putin is consi-dered as a full-fledged political reality. Today's powerful Russia, which has got a new life after the Cold War and the weak collapse period, and has a major impact on global developments including the Middle East, is not understandable except under this title. What inspired writers to analyze P...
متن کاملFocus, reentry, or "focal" reentry?
THE QUESTION WHETHER tachyarrhythmias are caused by enhanced impulse formation (“focus”) or by reentrant excitation (“reentry”) has been the subject of debate for more than a century. In 1887 McWilliam (12) was the first to suggest that disturbances in impulse propagation could be responsible for fibrillation, and he clearly envisaged the possibility that myocardial fibers could be reexcited as...
