Twenty-four hour ECG electrophysiology parameters and veloergometry in autonomic dyshormonal cardiopathy of various genesis

Abstract

The aim of the study was to specify electrocardiography changes and physical stress reactions inpatients with autonomous dyshormonal cardiopathy (ADC) of various genesis. In total, 175 ADC women were included: with menopause and pathological climax (n = 52), myoma uteri (n = 45), premenstrual syndrome, PMS (n = 36), and postcastrational syndrome (n = 42). Twelve-lead ECG was registered in supine position, 24-hour ECG monitoring was performed with ICAR system, veloergometry (in seated position) - with Formula veloer-gometer (Biomedica). Workload was increased permanently and gradually: starting from 25 Vt, by 25 Vt every 3 minutes. According to ECG data, no group, regardless of ADC genesis, demonstrated significant heart rate (HR) increase or depolarization/repolarization rates. The most typical ECG changes for all 4 groups were decreased or inverted T waves in left chest leads only or in all chest leads (prevalence 35, 71-40, 38 %). Myoma patients tolerated physical stress better than women in artificial menopause. All ADC patients demonstrated adequate HR and systolic blood pressure (СРВ) reaction to physical stress. Diastolic BP increase for PMS women was twice as high as in other groups. At the workload peak, repolarization processes improved, in some cases normalizing. Supraventricular and ventricular extrasystolia was most prevalent in myoma and PMS patients. Only ECG, Hotter monitoring and veloergometry in complex give complete data on myocardial electrophysiology in cardiopathy of any genesis. Therefore, no single test can be excluded from this diagnostic complex.
