Athletic heart and QT variability

Abstract

This review provides detailed data on the diagnosis, prevalence, classification, and etiology. The variety of causes leading to long QT syndrome (LQTS) creates difficulties in the differential diagnosis of this condition and, as a result, LQTS often remains outside the sports medicine physicians’ attention. As a result, it is necessary to introduce non-invasive screening methods for studying the cardiac electrophysiological characteristics and select high-risk groups.
