Coronary atherosclerosis and cardiac arrhythmias

Cardiac arrhythmias are associated with deterioration in patient’s quality of life, thromboembolic complications, and sudden cardiac death. Coronary atherosclerosis is often the cause of cardiac arrhythmias. Myocardial hypoxia and remodeling lead to impaired formation and conduction of the impulse and the development of ectopic rhythm. The article reviews the main pathogenetic mechanisms for various types of cardiac arrhythmias in patients with atherosclerotic coronary lesions.
