Summary:The term 'athletic heart syndrome' (AHS) is used to describe specific circulatory and morphological changes in individuals who participate in sports competitions. The syndrome is characterized by normal cardiac function and reversible myocardial remodelling.The incidence and severity of the post-COVID-19 cardiac pathology in active athletes are so far unclear. One of the complications involving the heart is myocarditis. We present a case of a 23-year-old rower after having a moderate COVID-19 infection. Electrocardiograms showed evidence of a shift in conduction and rhythm disturbances ranging from Group 1 (normal ECG findings) to Group 2 (abnormal ECG findings) on the background of an AHS. Echocardiography (with new methods of evaluating deformity - Global Longitudinal Strain) revealed an area with mildly reduced left ventricular deformity around the apex. To assess the subtle alterations in the myocardium, magnetic resonance imaging was used and focal myocarditis was detected. In our patient, considering the degree of severity of his COVID-19 infection - a moderate one, a decision was taken to perform a clinical and instrumental reassessment of his cardiovascular complications 6 months after the infection.This clinical case presents two substantial issues. First, is the AHS more susceptible to rhythm and conduction disturbances after a COVID-19 infection than that of a person who does not actively participate in sports? Second, what the reversibility or the definitive nature of these disturbances is, and how this impacts the prognosis associated with an active sporting activity.
