PERIOPERATING HIGH-RESOLUTION RHYTHMOCARDIOGRAPHY AT THE CORONARY SHUNTING IN CARDIOSURGERY

Results of application of heart rate variability analysis (HRV) are represented at coronary shunting (ACS) in patients with the coronary artery disease and angina pectoris. Purpose of research was application of the innovation method for evaluation of patient’s status at rational selection for cardiosurgical interventions, during anaesthesiology conducting operation and for observation of postoperative objective dynamics of patients. There were found the additional HRV indices specifying selection for ACS, predictors of risk the life-dangerous cardioarrhythmias. It was proved, that the high -resolution HRV-analysis is capable to show such dynamics of the patients status changes, which aren’t defined by standard methods. Disturbances of the heart rhythm were immediately modulated by surgical manipulations (n-98, p <0,001). At cardioplegic solution introduction on the background of HRV amplitude oppression exaltation of heart ventricles decreased, and on the ECG the amplitude “R” decreased too, but some time remained “P” with gradual depression of its height and augmentation of its duration. That may be estimated, as atrial flutter (AF) predictor. Than more were initial HRV and its reactions to stimuli during of selection of pts for intervention surgery operation, “P” and “PQ”, is lower Makruz’s index, the it is less probability of development of hemodynamically significant cardioarrhythmias (r=-0, 387-0,431), is more positive the end result of cardiac treatment. It supposes attention to the question of the earliest carrying out a planned cardiac intervention. The high-resolution computer analysis of HRV wave structure defining an actual condition of an autonomic and humoral-metabolic regulation of pacemaker activity of sinuatrial node, as an informative method of anesthesiology in management patients at the cardiac interventions.
