Intravenous metoprolol for the treatment of acute supraventricular tachyarrhythmias

Acta Cardiologica
R Stroobandt, H Kesteloot

Abstract

The antiarrhythmic effect of the cardioselective beta-adrenoreceptor blocking agent metoprolol, given intravenously, was studied in 20 patients with acute supraventricular tachyarrhythmias, including patients with congestive heart failure, acute myocardial infarction and complete bundle branch block. Six patients out of 9 with atrial fibrillation reverted to sinus rhythm. In all patients with atrial tachycardia and 3 out of 4 patients with atrial flutter restoration of sinus rhythm occurred. The drug was well tolerated and is of clinical value for the treatment of supraventricular tachyarrhythmias even in an elderly patient group.

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.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking 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.

Atrial Filbrillation

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

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.

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.
