Noninvasive diagnosis of dual AV nodal physiology in patients with AV nodal reentrant tachycardia by adenosine triphosphate test.
Atrioventricular nodal reentrant tachycardia (AVNRT) is a relatively common paroxysmal supraventricular tachycardia. This study investigated whether adenosine-5'-triphosphate (ATP) injection during sinus rhythm might be useful in the noninvasive diagnosis of dual AV nodal pathways. The study group consisted of 9 patients with slow/fast AVNRT and 11 control patients without antegrade dual AV nod...
متن کاملDouble retrograde atrial response after radiofrequency ablation of typical AV nodal reentrant tachycardia.
A double ventricular response resulting from a single atrial depolarization conducting down dual atrioventricular (AV) nodal pathways has been pt^viously well characterized.' "̂ However, a double atrial response as a result of a single ventricular depolarization conducting across dual retrograde AV nodal pathways has not been well described.^'' This case report describes a patient in whom a sing...
متن کاملTachycardia induced tachycardia: case report of right ventricular outflow tract tachycardia and AV nodal reentrant tachycardia.
Tachycardia induced tachycardia, or so called double tachycardia, is rare. A 34 year old woman is described who had a history of syncope, frequent extrasystoles, and episodes of non-sustained ventricular tachycardia, perceived as palpitation, without syncope. At electrophysiological study, during infusion of isoprenaline, an episode of non-sustained ventricular tachycardia arising from the righ...
متن کاملAV nodal reentrant tachycardia with a bystander Mahaim fiber.
A 13 year old boy had a wide QRS complex tachycardia. A discontinuity in the AV nodal functional curve was observed in the electrophysiologic study. The AV internal was prolonged in association with progressive ventricular preexcitation. At maximal preexcitation, the HV interval was -20 msec and the QRS complex was identical to that seen during clinical tachycardia. No VA conduction was found a...
متن کاملAV nodal reentrant tachycardia with Mahaim fiber conduction.
Paroxysmal tachycardia with widened QRS complexes was found in a 46-year-old woman. In sinus rhythm, the patient had electrocardiographic evidence of type B preexcitation with a left bundle branch block pattern. The resting PR interval (160 msec) and A-H interval (100 msec) were within normal limits, but the H-V interval (10 msec) was abnormally short. Programmed atrial extrastimuli at progress...
