Abstract

Tachycardia-induced cardiomyopathy can be defined as a condition characterized by myocardial dysfunction resulting from atrial or ventricular tachyarrhythmia, without underlying structural heart disease. It is a potentially reversible cause of heart failure and its most common presentation is dilated cardiomyopathy. When patients suffer from dilated cardiomyopathy with tachyarrhythmia, it is extremely important to recognize this potentially reversible condition. Here, we report the successful treatment of persistent supraventricular tachycardia with digoxin and atenolol during the treatment of a patient who presented in a coma.

Keywords: Tachycardia, Cardiomyopathies, Coma

Follow-up chest PA taken after recovery of cardiac function showed no cardiomegaly.
