Fig. Algorithm and results of the three-phase assessment of underage elite athletes aged 14–17, who have had SARS-CoV-2 infection
Table 1. Cardiovascular system alterations in underage elite athletes having a history of SARS-CoV-2 revealed during the first-phase assessment (see Figure). AVB — atrioventricular block; BEM — bicycle ergometry; PVC — ventricular extrasystole; LVEDD — left ventricular end-diastolic diameter; QTc — QT interval corrected using Bazett's formula (QT/√RR)
Table 2. Results of third-phase assessment of athletes having a history of SARS-CoV-2 infection (contrast-enhanced heart MRI). AVB – atrioventricular block; HRC — heart rate variability; BEM — bicycle ergometry; VT — ventricular tachycardia; PVC — ventricular extrasystole; LVEDD — left ventricular end-diastolic diameter; MTWA — microvolt T wave alternans; MRI — magnetic resonance imaging; HRT — heart rate turbulence; EF — ejection fraction; HM — Holter monitoring
