Abstract

Preliminary adaptation to short-term stress was shown to prevent the fall of the heart fibrillation threshold and its increased ectopic activity which is usually observed in experimental myocardial infarction. This protective effect involves an enhanced activity of the organism's antioxidant systems. On this basis, synthetic antioxidant ionol was applied to prevent disturbances of heart electric stability in infarction. Ionol completely prevented the decrease in the electric threshold and the increase in ectopic activity of the heart in experimental infarction, demonstrating thereby an anti-arrhythmic effect.

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.

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.

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.

Cardiac Electrophysiology

Cardiac electrophysiology is the study of electrical activities of the heart and includes the assessment, diagnosis, and treatment of cardiac events. Find the latest research on cardiac electrophysiology here.

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.
