Studied indicators in the group of healthy individuals ( n = 19) using functional tests (Shtange, Valsalva and tensor), the 2 nd group of patients ( n = 55) - with chronic obstructive pulmonary disease (COPD) at the age of 54 ± 8 yrs (32 of them with berodual or symbicort test) and the 3 rd group - with ACA on the background of coronary artery disease and hypertension at the age of 58 ± 6 yrs ( n = 30) time Analysis of intra- and interatrial conduction with ACA and COPD showed similar violations of MCG in these groups, which can be induction and maintenance factors of atrial fibrillation. MCG method can be used to assess the electrophysiological status of the myocardium of the Atria.MagnetocardiographyP-wavechronic obstructive pulmonary diseaseparoxysmal of atrial fibrillationмагнитокардиографияР-зубецхроническая обструктивная болезнь легкихпароксизмальная форма мерцательной аритмии
