The aim is the studying of the significance of the heart rate variability (HRV) characteristics during the interpretation of the veloergometric (VEM)tests results in patients with ischemic heart disease. 243 patients with the stable angina of the II-III functional class (49 ± 8 years) were involved in the studying. The evidence of coronary pathology was assessed with the help of selective coronary angiography. Results of VEM testing, Doppler echocardiography and spectral analysis of HRV were analyzed. Registration of R-R chains was performed during 3 min in the relaxed condition and in 90 sec after the beginning of 25 Watt stage of the VEM test. Frequency assessments of HRV were obtained with the help of the parametric method of spectrum construction. The results showed, that using of the HRV spectrum indices allows to raise the diagnostic reliability of VEM tests. Negative result of a VEM trial is characterized by the low level of reliability and cannot be used as an index of absence of the coronary channel damage.
