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 کاملElectrophysiological effects and clinical efficacy of propafenone in children with recurrent paroxysmal supraventricular tachycardia.
Twenty-four patients aged 10.1 +/- 4.5 (mean +/- SD) years with recurrent paroxysmal supraventricular tachycardia underwent an electrophysiological study. Eleven patients had an overt and seven had a concealed accessory connection; six patients had no accessory connection. An orthodromic reciprocating tachycardia was inducible in 17 of 18 patients with an accessory connection, and an atrioventr...
متن کاملUnmasking of left free wall ventricular preexcitation by His bundle ablation.
His bundle ablation was performed in a 48 year old man with drug refractory orthodromic atrioventricular reentrant tachycardia and paroxysmal atrial fibrillation. Reentry was caused by a left free wall concealed accessory pathway. Interruption of the His bundle by low energy direct current shock (25 J) was quickly followed by anterograde conduction via the accessory pathway, with various forms ...
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...
