Arrhythmias in cardiomyopathy

Abstract

The morbidity and mortality of patients with cardiomyopathy are related to either pump failure or arrhythmia-induced death or decompensation. Cardiomyopathy can also be induced by arrhythmias. Adequate and prompt therapy of arrhythmias is an essential part in the multidisciplinary approach to these patients. We review the arrhythmias seen in patients with multiple types of cardiomyopathy and the therapeutic options available. The implantable cardioverter defibrillator has become the main therapy for sudden cardiac death prevention. We also review the different oral antiarrhythmics available. Ablation therapy has become an effective means of curing or controlling arrhythmias. Finally, we discuss arrhythmias in specific cardiomyopathies and patient with left ventricular assist devices.
