Abstract

Recent developments in our understanding of atrial fibrillation (AF) have focused on the key role of pulmonary vein initiators of multiple wavelet reentry in the atria. Percutaneous catheter ablation of atrial fibrillation is commonly performed by electrical disconnection of pulmonary vein myocardium from the left atrium. As a result, pulmonary vein foci can no longer drive the atria into fibrillation. At present, the procedure is offered to patients with paroxysmal atrial fibrillation refractory to multiple antiarrhythmic agents. For patients with persistent atrial fibrillation, supplementary linear lesions in the left atrium may be necessary. Success rates (AF elimination) are 90% without drugs in case of paroxysmal atrial fibrillation and 80% for persistent atrial fibrillation. Complications including pulmonary vein stenosis are uncommon.

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.

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.
