Background. Low-frequency (LF) oscillations in heart rate (HR) are largely an index of baroreflex gain. Controlled 0.1 Hz breathing maybe used as input stimuli for study of this resonance phenomenon in LF oscillations in HR. The aim of this study was the investigation of the dynamic characteristics of LF oscillations in the heart rate (HR) of chronic heart failure (CHF) patients during bicycle exercise (BE) tests, under 0.1 Hz controlled breathing. Methods. Forty five male patients aged 50±3 years with left ventricle ejection fraction (EF) <50% and 35 male patients aged 52±6 years with EF>50% participated in the study. BE tests were performed for all participants. Five-minute recording of R-R intervals was performed first in sedentary posture and in 25 W load stage of BE test. The frequency estimates of heart rate variability in LF spectrum bands were obtained. Results. Under the load rising till 25 W in CHF patients with EF<50%, consequent depression of LF band power was observed 2-3 times in comparison with the relaxed condition. There was no similar significant expressed dynamic in the group with EF>50%. Conclusions. The stability of LF oscillations in HR to low-intensity loads depends from the severity of myocardial contractility damage. The power dynamic of 0.1 Hz component of the heart rate variability spectrum may be considered an independent index of dynamic stability of the heart autonomic control in CHF patients.

The research goal is to study the impact of various schemes of antibacterial therapy in the postoperative period in patients after cataract phacoemulsification with distant thermography. Under observation there were 68 patients with cortical initial cataract. All patients were subjected to cataract phacoemulsification. Patients were divided into 2 groups: 34 patients of the first group after the operation dropped into the operated eye medication «Oftaquiks» 1 drop 5 times a day for one day before surgery and for 5 days postoperatively. 34 patients from the second group as an antibacterial drug received medication "Cipromed" in a similar way. Inflammatory reaction in postoperative period in the first group was not evident. In the second group the presence of inflammatory reaction of various degrees was revealed. Period of its reduction was 6,3 ± 2 days. The temperature difference between the non-operated and operated eye in the 3d day in most cases was less than 1 day after surgery. In the first group of patients the average temperature difference in the 3d day after surgery was 0.35 ± 0.21 ° C, and in the second group of patients - 1.3±0.83°C. Advantages of dynamic thermal imaging method for monitoring the state of the eye, including the analysis of time dependencies of temperature in the process of natural load test, which allows to select the optimal drug correction of postoperative cataract pha-coemulsification were revealed
