Potassium: its relevance for arrhythmias complicating acute myocardial infarction.

Journal of Cardiovascular Pharmacology
R W CampbellA Murray

Abstract

Potassium plays a critical role in cellular electrophysiology. Clinically, serious cardiac rhythm disturbances are a well-recognised complication of profound hypokalaemia. Recent research has focussed on the possibility that serious ventricular arrhythmias, particularly ventricular fibrillation, might be caused by the hypokalaemia that occurs in the acute phase of myocardial infarction. Proof of this association would be a strong impetus to develop interventions that might stabilise potassium values in an attempt to produce an antiarrhythmic effect.

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.

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.

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.
