title: Low atrial tachycardia as primary cause of the heart failure complicating congestive cardiomyopathy.
abstract: A 50-years-old man with severe heart failure was diagnosed to have congestive cardiomyopathy and low atrial tachycardia at a fixed rate of 103 bpm. Conventional therapy for heart failure exerted a beneficial effect but complete clinical improvement was achieved only by reducing the rate of low atrial tachycardia with amiodarone. This suggests that in this situation tachycardia itself played a main role in the genesis of hemodynamic derangement.
