Objective. Studying the influence of simpato-vagal balance in the development of atrial fibrillation in patients with chronic obstructive pulmonary disease. Material and methods. The assessment of parameters of heart rate variability and turbulence in patients with chronic obstructive pulmonary disease with or without atrial fibrillation. Surveyed 66 patients (16 with atrial fibrillation, 50 without it). All patients underwent ECG monitoring with the SEERLight apparatus and the MARS system, spirometry, echocardiography. During the evaluation of the results, there were no statistically significant changes in the frequency parameters of heart rate variability depending on the presence of atrial fibrillation in these patients. VLF (20.46±60.596 mps2 compared with 29.60±22.735 mps2; p>0.05) and LF (34.40±0.387 mps2 compared with 22.36±19.197 mps2; p>0.05) and HF (10.56±5.192 mps2 compared with 14.55±9.774 mps2; p>0.05) and LF/HF (1.37±0.518 compared with 1.47±0.422; p>0.05). There were no significant changes observed in temporary parameters: NN-mean (818.4±122.53 ms compared with 846.1±126.20 ms; p>0.05), SDNN (98.2±30.37 ms compared with 118.7±56.35 ms; p>0.05), SDANN (87.5±31.58 ms compared with 97.13±46.81 ms; p>0.05), ASDNN (41.7±14.13 ms compared with 55.9±38.22 ms; p>0.05), rMSSD (30.7±15.12 ms compared with 38.2±25.02 ms; p>0.05), pNN50m (9.9±10.73 compared with 13.7±17.57; p>0.05). Conclusions. The development of atrial fibrillation in patients with chronic obstructive pulmonary disease is not the result of violation of vegetative balance.
