Aim. To assess the dynamics of heart rate variability (HRV) parameters under treatment by ivabradine in patients with stable angina after coronary bypass surgery (CBG) with test of fixed respiration tempo (FRT).Material and methods. Totally, 26 males studied, with stable angina II-III functional class, after CBG, using hardware-software complexes.Results. The FRT test in postCBG patients under ivabradine treatment reveals 2 main types of reaction: 1 — positive stable increase of HRV parameters during the test, 2 — U-shaped pattern of parameters’ dynamics: decrease in 6-second test, and increase further in 12-second test.Conclusion. The FRT test has practical value, making physician, by the parameters as SDNN or mean rhythmogram variation, to derive conclusions on the adequacy of rehabilitation of patients and to correct the dosage of medication.
