Annotation

The influence of sports activity on the cardiovascular system is accompanied by physiological adaptation of the body. Intense physical activity, far beyond the capabilities of the body, can lead to structural changes or remodeling of the athlete’s myocardium. Based on the mechanisms of electrical heterogeneity of the ventricular myocardium, the most probable ECG indicators reflecting this process are considered. Clinical studies have shown high predictive power of these indicators in detecting fatal and non-fatal cardiovascular events and sudden cardiac death. It was found that the speed indicators of the electrical activity of the heart are the earliest marker of cardiac arrhythmias and conduction disorders. Risk factors — arterial hypertension, smoking, hypercholesterolemia and overweight — are associated with a decrease in the rate of electrical activity of the heart and an increase in myocardial heterogeneity. The review is devoted to the study of myocardial heterogeneity and is aimed at attracting the attention of doctors, physiologists, biologists, researchers and developers of ECG computer analysis programs to prognostic indicators that have been widely discussed in foreign literature over the past decades, but are not used by domestic specialist
