Development of multiform ventricular tachycardia during atrioventricular nodal reentrant tachycardia.

Development of multiform ventricular tachycardia during atrioventricular nodal reentrant tachycardia.

A woman of 18 presented with a supraventricular tachycardia, subsequently shown to be caused by atrioventricular nodal reentry, which abruptly deteriorated to a multiform ventricular tachycardia. She had not received any antiarrhythmic drugs nor did she have any of the disorders that are usually associated with this atypical ventricular tachycardia.

Familial Occurrence of Atrioventricular Nodal Reentrant Tachycardia.

BACKGROUND Atrioventricular nodal reentrant tachycardia (AVNRT) is considered a sporadic disease occurring in ≈22.5 cases per 10 000 in the general population. We define the prevalence and characteristics of familial AVNRT among patients who underwent radiofrequency ablation. METHODS AND RESULTS Ablation reports of all patients with familial AVNRT (at least 2 first-degree family members) who ...

Atrioventricular nodal block with atrioventricular nodal reentrant tachycardia ablation.

Catecholamine-dependent atrioventricular nodal reentrant tachycardia.

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 ...
