Heart rate variability analysis at coronary artery disease and angina pectoris.

The purpose of this study was to present results of special examination and prospective observation of patients with coronary artery disease (CAD) and angina pectoris (AP) in practical cardiology. Except standard cardiological methods, we used high-resolution rhythmocardiography and apparatus-program complex for registration and analysis of the heart rate variability. There was an evaluation of the autonomic and humoral-metabolic regulative influences on pacemaker activity of the heart sinus node in 273 patients selected by criteria of including-excluding patients with CAD and AP.
