Physiological substrate for antidromic reciprocating tachycardia. Prerequisite characteristics of the accessory pathway and atrioventricular conduction system.
BACKGROUND Although the anatomic "substrate" for the occurrence of antidromic reciprocating tachycardia (ART) has been previously examined, the underlying physiological substrate for this unusual arrhythmia in patients with the Wolff-Parkinson-White syndrome has not been thoroughly characterized. METHODS AND RESULTS The electrophysiological properties of the accessory pathway and normal ventr...
متن کاملFlecainide-induced incessant orthodromic atrioventricular reentrant tachycardia in Wolff-Parkinson-White syndrome: Uneven depression of accessory pathway conduction
Introduction During orthodromic atrioventricular reentrant tachycardia (AVRT), ventricles are activated anterogradely through the atrioventricular node and retrogradely through an accessory pathway (AP). Antiarrhythmic drugs are initially used to prevent recurrences of AVRT, whereas catheter ablation is frequently performed as a definitive treatment. Occasionally, catheter ablation can be “proa...
متن کاملAtypical patterns of retrograde conduction over accessory atrioventricular pathways in the Wolff-Parkinson-White syndrome.
Patterns of ventriculoatrial conduction have been used to distinguish retrograde conduction over an accessory atrioventricular pathway from that over the normal atrioventricular conduction system. Ventriculoatrial conduction at a constant interval during incremental ventricular pacing and during progressive prematurity of ventricular extrastimuli has been considered characteristic of conduction...
متن کاملVentriculo-atrial conduction time during reciprocating tachycardia with intermittent bundle-branch block in Wolff-Parkinson-White syndrome.
Records from patients with the Wolff-Parkinson-White syndrome were reviewed with particular emphasis on the occurrence of bundle-branch block aberration during reciprocating tachycardia and the significance of this observation with respect to accessory pathway location. Increase by greater than 25 ms in the ventriculoatrial interval during reciprocating tachycardia with bundle-branch block, whe...
متن کاملPhase analysis in the Wolff-Parkinson-White syndrome with surgically proven accessory conduction pathways: concise communication.
Twenty-one patients with the Wolff-Parkinson-White (WPW) syndrome who underwent surgical division of the accessory conduction pathway (ACP) were studied by gated blood-pool scintigraphy. In each case, a functional image of the phase was generated, based on the fundamental frequency of the Fourier transform. The location of the ACP was confirmed by electrophysiologic study, epicardial mapping, a...
