The objective of this article is to review supraventricular arrhythmias emphasized the importance of atrial fibrillation (AF) and its novel therapeutic approach in dogs. Supraventricular arrhythmias include disturbances of impulse formation at sinus node, atria and junctional area or alterations of impulse conduction within the chamber above ventricles. Among those supraventricular arrhythmias,...

We present a case of a rare complication of transvenous right ventricular pacing by temporary pacing wire causing iatrogenic interventricular septal perforation and left ventricular pacing in a 69-year-old man who was referred for recurrent syncope with sinus arrest.

BACKGROUND Catecholaminergic polymorphic ventricular tachycardia is a disease characterized by ventricular arrhythmias elicited exclusively under adrenergic stress. Additional features include baseline bradycardia and, in some patients, right ventricular fatty displacement. The clinical spectrum is expanded by the 2 families described here. METHODS AND RESULTS Sixteen members from 2 separate ...
