Abstract:
The social significance of myocardial infarction is determined not only by the high mortality
of patients, but also by the fact that a significant part of them subsequently develop heart failure
(HF) and cardiac arrhythmias (CHD), which worsen the quality of life and limit the ability to work
in hospital. CMECG is one of the most promising approaches for identifying groups at increased
risk of developing IBS and AMI, predicting the course of the pathological process, and developing
complications. The purpose of the study was to study the prevalence of cardiac arrhythmias in
patients who suffered Q-wave myocardial infarction. The study included 80 male patients with
primary Q-wave MI aged from 29 to 60 years (average age 50.8±0.98 years), no more than 10 days
old. All patients underwent CMECG. The analyzed CMECG parameters included average hourly and
average daily heart rate, circadian index (CI); location of the S-T segment relative to the isoline and
its configuration; polarity and amplitude of “T” waves; structure of heart rhythm disturbances.
