Abstract

The efficacy of intravenous flecainide and cibenzoline acetate in the reduction of atrial rhythm disorders was compared in two groups of 30 patients. These arrhythmias are divided in 31 atrial fibrillation, 11 tachy-systoles, 18 atrial flutters. Parenteral administration of the anti-arrhythmic drug over a 24 hour-period is preceded by a bolus injection of 1.5 mg/kg of flecainide acetate for group I, and a bolus of 1 mg/kg of cibenzoline for group II. The overall efficacy of the two molecules is comparable (53%) as well as the reduction of the atrial fibrillations (65% vs 57%). Flecainide acetate seems more effective in treating effectively atrial tachycardias (66.6% vs 40%), and cibenzoline is more effective in the treatment of atrial flutters (54% vs 14%). The functional, electrical and haemodynamic tolerance has always been good in both group, except in 2 patients, because of the indirect pro-arrhythmic effect of cibenzoline. We are concluding that the efficacy of both molecules is satisfactory and we advocate their use, as first intention, in recent and idiopathic atrial fibrillation; it seems that cibenzoline is more effective on ischemic cardiopathies and flecainide acetate is more effective on valvular cardiopathies.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

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.

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. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
