HOLTER MONITORING OF ECG IN W3OMEN WITH ACUTE MYOCARDIAL INFARCTION IN THE PERIMENOPAUSAL PERIOD

Abstract

Aim. To study the results of Holter monitoring of ECG in women with acute myocardial infarction in the perimenopausal period.

Materials and methods. The work is based on the study of clinical and functional features of ischemic heart disease of 99 women of the 45-60 age range in the perimenopausal period during acute myocardial infarction.

Depending on a level of menstrual function impairment patients were divided into 2 groups. The first group consisted of 50 women in the premenopausal period including women with the irregular menstrual cycle in last 3-11 months (average age 45,1±0,6). The second group consisted of 49 women (average age 60,6±0,6) without menstrual function during one year or women in the postmenopausal period.

Daily monitoring of ECG was held with “Astrocard Holtersystem” equipment in three leads V4, V 5, V6 that take electric potentials from a front, lower and lateral walls of the left ventricle.

Results. According to the results of study women with acute myocardial infarction in the perimenopausal period can have episodes of heart rhythm disturbances, paroxysms of supraventricular tachycardia, supraventricular extrasystole, atrial fibrillation, atrial flutter and ventricular extrasystoles of high grades by Loun- Wolff (II-V cl).

Conclusion. The study showed a high frequency of heart rhythm disturbances, which is 88% in both study groups. That is a sign of high risk of cardiovascular complication, which is myocardial infarction in this case.
