We studied specific features of heart rhythm disturbances observed during outpatient rehabilitation of 432 patients after first myocardial infarction. In 94 of these patients (21.8%) we diagnosed obstructive sleep apnea syndrome (OSAS). We noted substantial preponderance of pathologic ectopy related to OSAS with most significant detection of frequent ventricular extrasystoles. Their paired variant and polymorphic forms in patients with OSAS were 3.4 and 7.4 times, respectively, more frequent than in patients without OSAS. Frequency of ventricular ectopy rose with increase of severity of OSAS and was maximal during nocturnal hours. Analysis of correlations revealed association between OSAS and frequencies of ventricular and supraventricular extrasystoles. After myocardial infarction patients should be thoroughly examined for timely detection of OSAS and corresponding correction of their rehabilitation program.
