Abstract

The aim of this prospective, non-randomized interventional study was to assess electrophysiological effects, efficacy and safety of intravenous propafenone in termination of atrioventricular nodal reentrant tachycardia (AVNRT) and orthodromic atrioventricular reentrant tachycardia (AVRT). This single-center study was carried out at Department of Cardiology, Sestre milosrdnice University Hospital in Zagreb, Croatia, between January 1, 2005 and December 31, 2006. Eligibility requirements were fulfilled by a total of 70 patients with AVNRT (n=37) and AVRT (n=33). The intervention consisted of the electrophysiological study aimed at inducing tachycardia, followed by intravenous administration of 2 mg/kg propafenone in both groups. The main outcome measures were safety and efficacy of 2 mg/kg intravenous propafenone in tachycardia termination and re-induction. Out of 37 patients with AVNRT, propafenone managed to terminate it in 28 (75.7%) patients, while tachycardia was not inducible in 25 (67.56%) patients. Out of 33 patients with AVRT, propafenone managed to terminate AVRT in 29 (87.9%) patients, while tachycardia was not inducible in 22 (66.66%) patients. The overall propafenone efficacy in tachycardia termination was 81.42%. No...Continue Reading

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
