Prexcitation. Understanding the mechanism of arrythmia will cause make diagnosis and plan of treatment.Division of Cardiology and Vascular Medicine, Universitas Padjadjaran, Dr. Hasan Sadikin Hospital, Bandung, Indonesia. Binawaluya Cardiac Center, JakartaIntroductionParoxysmal Supraventricular Tachycardia with sudden onset and termination is reasonably frequent. The big bring about are AVNRT (approximately to of situations), AVRT (roughly of circumstances), and AT (around of circumstances). Preexcited tachycardia take place in up to of patients with preexcitation syndromes. The usual mechanisms of typical preexcited tachycardia are atrial flutter or tachycardia, antidromic reciprocating tachycardia, and standard atrioventricular (AV) nodal reentry with bystander accessory pathway (AP). We present a unusual mechanism of PSVT, atypical (fastslow) AV nodal reentry with bystander septal AP. Case ReportA year
old female had recurrent episodes of palpitations. She had non documented Paroxysmal Supraventricular Tachycardia and her resting electrocardiogram was normal. Electrophysiological study shown concentric retrograde atrial conduction with appropriate ventricular pacing. Tachycardia was induced for the duration of atrial extrasystole which shown ventriculoatrial conduction ms with AHHA much less than a single. We’ve performed Zypes methode (Hyssynchronous Ventricular Extrastimulation) and Para Hisian pacing to differentiate in between atypical AVNRT and AVRT due to septal Accessory Pathway. Zypes test showed atrial advencement and Para Hisian Pacing showed stimulation atrial time was just about the identical which confirmed the existence of septal Accessory Pathway. The accessory pathway can’t be mapped through atrial pacing nor ventricular pacing. The YHO-13351 (free base) site decremental conduction and presence of retrograde dual atrioventricular nodal physiology giving the clue of atrioventricular nodal reentrant tachycardia as one of several mechanisme of tachycardia. So we ablated slow nodal pathway by radiofrequency. Following ablation, there was no proof of retrograde dual AV nodal physiology and no tachycardia was inducible by atrial and ventricular pacing nor by isoproterenol infusion. The patient was remained arrhytmia absolutely free over a month stick to up. This case present retrograde dual AV node physiology in the presence of septal accessory pathway. It’s significant to recognize presence of AP as a bystander in preexcited atypical AVNRT. Following the ablation of slow nodal pathway, no tachycardia was inducible. So we conclude the mechanism of this PSVT was Atypical AVNRT with bystander septal accessory pathway.PP .
