The most common types of arrhythmias were supraventricular tachycardia (44%, the 1st group) and premature contractions (40%, the 2nd group). Less frequently diagnosed ventricular tachycardia (6%, the 3dgroupe) and bradyarrhythmia (10%, the 4th group). A more unfavorable course of pregnancy was in the 4th group myometrial hypertonici (29%, p=0,001), the only artery of the fetal mbilical cord (14%, p=0,036). Median pregnancy duration was 39 (38;39,5) in all groups. Vaginal delivery was in 54 (75%) cases, Cesarean delivery - in 18 (25%) cases. Birth weight and 5 minute Apgar's score were 3378 (3023;3917,5) and 8,9 (7,8;9) in the 1st group, 3460 (3016,5;4020) and 8,9 (7,8;8,9) - in the 2nd group, 3430 (3300;3650) and 8,9 (8,9;8,9) - in the 3dgroupe, 3334 (2870;3530) and 8,9 (7,9;9) - in the 4th group (p>0,05). There were no maternal and neonatal death. The most common type of arrhythmias in pregnant women without structural heart disease were supraventricular tachycardia (44%) and premature beats (40%). It is associated by good pregnancy course and outcomes in cases qualified manadgment.The aim of our study was to study and analyze the electrophysiological indicators of rhythm disturbances in heart failure in elderly people who participated in the elimination of the consequences of the Chernobyl accident in the distant period. In order to assess the functional features, 50 elderly patients (65-74 years old) who participated in the liquidation of the consequences of the Chernobyl accident were examined. Patients were divided into 4 groups depending on the length of stay in an environmentally disadvantaged zone group 1 (April-June 1986) - 8 (16%) people;
