The Electrical Activity of the Heart during Ventricular Repolarization and Types of the Remodeling of the Athlete`s Heart

Abstract

The aim of this work was to investigate the electrical activity of the athletes’ hearts with different types of the left ventricular remodeling, as well as a control group of untrained people, by the body surface potential mapping before and immediately after exercising. The study of the heart’s electric field in athletes of the same sex, age and sport qualification, but different sport disciplines, showed that the reaction of the heart to physical activity is reflected in different changes of the amplitude-temporal characteristics of the extremes on the body’s surface in athletes with eccentric and concentric myocardial remodeling.
