An unusual case of atrioventricular nodal reentrant tachycardia precipitated by ethanol ingestion is presented. Programmed atrial and ventricular stimulation failed to induce the tachycardia during control conditions or after atropine administration. This failure to induce tachycardia was related to the absence of ventriculoatrial conduction. A low-dose isoproterenol infusion allowed induction ...

Radiofrequency (RF) catheter ablation became first-line therapy for supraventricular tachycardia in patients with Wolff-Parkinson-White syndrome1–5 and atrioventricular (AV) nodal reentrant tachycardia (AVNRT)6–11 in the early 1990s. High ablation success ( 90%) and low complication rates ( 5%) were found by numerous investigators.1–11 This article describes these ablation techniques with a foc...

The classic features of Wolff-Parkinson-White syndrome developed in a 49 year old man after he was given the heart of a donor who had had a normal electrocardiogram. The recipient showed type A pre-excitation on the surface electrocardiogram and clinically important paroxysmal supraventricular tachycardia. An electrophysiological study showed a left sided accessory pathway and dissociation betw...

background: this study was done to assess the efficacy and adverse effects of the different doses of adenosine in the pediatric age group with respect to multiple patient variables.   methods: over a period of 1 year, 86 occasions of supraventricular tachycardia (svt) were treated with adenosine in 81 infants and children aged between 18 days and 12 years (median of 1.3 years, sd=3). adenosine ...

We tested the effectiveness and safety of i.v. diltiazem in the management of paroxysmal supraventricular tachyarrhythmias in 39 patients, 21 with organic heart disease and seven in heart failure. Fifteen patients presented with supraventricular tachycardia, 12 with atrial fibrillation and 12 with atrial flutter. End points were conversion to sinus rhythm or slowing of the ventricular rate to 1...

background supraventricular tachycardia (svt) is the most frequent arrhythmia requiring a medical treatment in neonates. objectives the aim of our study was to evaluate and manage neonatal supraventricular tachycardia. methods this study was performed on 22 newborns that were diagnosed with svt at two neonatal intensive care units (nicu) in south west of iran from october 2012 to october 2015. ...

The efficacy of quinidine versus lidoflazine therapy was compared in the maintenance of sinus rhythm after electrical cardioversion for atrial flutter or fibrillation in a group of 35 patients. Both quinidine and lidoflazine were relatively ineffective in maintaining sinus rhythm after cardioversion. Lidoflazine was also used to prevent supraventricular and ventricular tachycardias in a miscell...
