The purpose of these researches was evaluation of the high-resolution Rhythm Cardiography (ECG) possibilities for definition of an actual cardiovascular status of the operated patients with angina pectoris during carrying out of the Coronary Artery Bypass Graft Surgery (CABGS) for a myocardial revascularization. These investigations were made out by means of the hardware-software complex KAP-RC-02 -"Micor" with a monitor record and the analyses of the Heart Rate Variability (HRV) in Time-Domain and Frequency-Domain. Monitor records were made in various stages CABGS in 123 patients. In results, the RCG manifested oneself as the quite adequate and perspective method of the definition of the actual cardiovascular status during carry out for cardiac revascularization in patients with angina pectoris. Also the data of the HRV studying at the CABGS testify about possibilities of the RCG definition of the high risk of life-dangerous cardio arrhythmias during operation, about different changes of the Sinoatrial heart Node (SN) regulation, and concerning the symptoms of the lethal outcome of CABGS. The loss of the peripheral autonomic sympathetic and parasympathetic control in SN in the form of an autonomic cardioneuropathy syndrome is the predictor of the intraoperative complications during and after CABGS. The obtained data at the RCG monitoring HRV record assume about wide prospects of the high-resolution RCG using in the cardiac surgery as a whole. Actual multiple deregulations of SN pacemaker activity testified to its adequate to a pathophysiology of each period of this cardiac operation, according to initial ischemic defeats and localization of the cardiosurgical manipulations during CABGS.
