title: [Tachycardiomyopathy induced by atrial fibrillation].
abstract: A 56 year old woman with a previously normal heart developed severe left ventricular dilation and hypo-contractility after a few weeks of a refractory, high ventricular rate atrial fibrillation. Reduction of heart rate with verapamil resulted in a rapid normalization of myocardial contractility.
