Effect of antireceptor antibodies in dilated cardiomyopathy on the cycling of cardiac beta receptors.

abstract：:The purpose of this study was to assess the recovery of the left ventricular pressure (PLV), and the incidence and type of arrhythmias after effective low-dose defibrillation (Imax = 18-70 A) in healthy hearts and in hearts with acute myocardial infarction (AMI) in the intact dog. In fifteen dogs 84 episodes of fibril...
