Ventricular arrhythmias in idiopathic dilated cardiomyopathy.
Twenty four hour ambulatory electrocardiograms were recorded in 60 patients with idiopathic dilated cardiomyopathy. The diagnosis was based on clinical, laboratory, and cardiac catheterisation findings. All patients had a left ventricular ejection fraction less than 0.55; in 39 it was less than 0.40. Ventricular extrasystoles were evident in all patients: they were rare in 11 (18%), moderately ...
متن کاملArrhythmias in dilated cardiomyopathy.
Sixty-five patients with dilated cardiomyopathy underwent 24 hour electrocardiographic monitoring: 62 (95.4%) showed ventricular arrhythmias and 52 (80%) complex ventricular arrhythmias (multiform ventricular extrasystoles, paired ventricular extrasystoles and ventricular tachycardia). Complex ventricular arrhythmias correlated significantly with some haemodynamic indices of ventricular dysfunc...
متن کاملMechanisms underlying spontaneous and induced ventricular arrhythmias in patients with idiopathic dilated cardiomyopathy.
BACKGROUND To define the electrophysiological mechanism(s) of inducible and spontaneously occurring ventricular arrhythmias associated with nonischemic cardiomyopathy, 3-dimensional intraoperative mapping from 156 intramural sites was performed in 6 patients with idiopathic dilated cardiomyopathy undergoing cardiac transplantation. METHODS AND RESULTS Electrode density was sufficient to deter...
متن کاملArrhythmias and Dilated Cardiomyopathy
Dilated cardiomyopathy (DCM) is the most common cause of heart failure and cardiac transplantation, and is among the most common diagnoses requiring hospitalization in North America. Approximately 4.7 million people in the United States have heart failure, and approximately 550,000 new cases are diagnosed annually (1). The 5-year mortality rate among patients with heart failure is close to 50% ...
متن کاملIdiopathic Dilated Cardiomyopathy
Background Autoantibodies against the 81-adrenoceptor have been detected in the sera of patients with idiopathic dilated cardiomyopathy (DCM). The mechanisms by which these autoantibodies can alter normal receptor function are investigated, and the results are interpreted in the light of the beneficial effects of P1-blockade in some of these patients. Methods and Results Autoantibodies against ...
