Usefulness of low-dose dobutamine stress echocardiography in predicting recovery of poor left ventricular function in atrial fibrillation dilated cardiomyopathy

Am J Cardiol. 1999 Jun 15;83(12):1668-71, A7. doi: 10.1016/s0002-9149(99)00177-0.

Abstract

Assessment of contractile reserve was performed in 16 patients with dilated cardiomyopathy and chronic atrial fibrillation. In this prospective study, low-dose dobutamine echocardiography could predict recovery of left ventricular dysfunction and could identify tachycardiomyopathy before restoration of sinus rhythm.
