Abstract

The anti-arrhythmic efficacy of barucainide, a new class IB anti-arrhythmic agent, was evaluated in an open-label therapeutic study in a total of 15 patients with coronary artery disease. The majority of patients had a history of myocardial infarction. After a 3-day placebo run-in period barucainide was administered at a dose of 150 mg b.d. for 5 days followed by a 4-day placebo wash-out period. 24-h Holter monitorings were recorded in the run-in period, on day 4 of the treatment period, and on day 3 of the wash-out period. In addition, plasma levels were determined in all three periods. Statistical evaluation of the 24-h arrhythmia analyses revealed a decrease of premature ventricular contractions (PVCs) in all treated patients. Before treatment PVCs occurred at a median of 92.4/h (minimum 19/maximum 1537 PVCs/h); this value was reduced during treatment to a median of 7.9 (0/427) PVCs/h (p less than 0.01). A similar result was also found for the couplets which decreased significantly from a median (min/max) of 0.6 (0/11)/h before treatment with barucainide to 0.1 (0/3)/h after treatment (p less than 0.05). In 10 of 15 patients premature ventricular contractions were reduced by more than 80%. Ventricular tachycardia present in ...Continue Reading

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.

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.
