Key result
Amiodarone converted 66.7% of patients to sinus rhythm and significantly improved mean ejection fraction from 36.2% to 51.2% in patients with tachycardia-induced cardiomyopathy due to non-valvular atrial fibrillation.
Why the study?
Does amiodarone improve cardiac function and convert to sinus rhythm in patients with tachycardia-induced cardiomyopathy due to non-valvular atrial fibrillation?

Does amiodarone improve cardiac function and convert to sinus rhythm in patients with tachycardia-induced cardiomyopathy due to non-valvular atrial fibrillation?
Amiodarone effectively converts non-valvular atrial fibrillation to sinus rhythm and improves left ventricular ejection fraction in patients with tachycardia-induced cardiomyopathy.
Amiodarone may aid rhythm control in tachycardia-induced cardiomyopathy; hypothesis-generating case report requiring randomized confirmation.

Yom et al. (2001) conducted an observational in Tachycardia-induced cardiomyopathy due to non-valvular atrial fibrillation (n=27). Amiodarone vs. Baseline was evaluated on Ejection fraction (%) (p=<0.01). Amiodarone converted 66.7% of patients to sinus rhythm and significantly improved mean ejection fraction from 36.2% to 51.2% in patients with tachycardia-induced cardiomyopathy due to non-valvular atrial fibrillation.
