Risk Of Sudden Death In Athletes: Electrocardiographic Criteria

Modern sports of high achievements require the maximum mobilization of functional reserves, compensatory and adaptive reactions of an athlete. Thus, significant physical activity can lead to pathological changes in the electrocardiogram. According to the consensus of the European Union of 2016, physiological changes in the electrocardiogram include: sinus bradycardia, sinus arrhythmia, supraclavicular extrasystole, atrioventricular blockade of the I st., incomplete blockade of the right foot of the Gisson bundle, separate criteria for left ventricular hypertrophy, syndrome of early ventricular repolarization, and pathological signs include inversion T-wave, depression of the segment ST, pathological teeth Q, complete blockade of the left leg of the Gisson, violation of intraventricular conduction, deviation of the electrical axis of the heart to the left, signs of enlargement of the left atrium, right ventricular hypertrophy, preexcitation syndrome, prolonged or shortened QT interval, Brugada syndrome, bradycardia <30/min, atrial or ventricular tachyarrhythmia. The frequent ventricular extrasystole which is defined by sports doctor. The athlete Seattle criteria found in the form of sinus bradycardia is greater than 30 doses per minute, incomplete blockade of the right leg of the Giss's bundle, some signs of GFR, early ventricular repolarization, ectopic atrial rhythm, atrioventricular blockade of the II st. are considered to be manifestations of adaptation to regular physical activity. Pathological changes are: inversion of the T wave, complete blockade of the left leg of the Gisson, violation of intravaginal conduction with duration of QRS> 140 ms, left atrial pathology, right ventricular hypertrophy, Wolf-Parkinson-Wyth syndrome, corrected QT ≥470 ms in men and ≥480 ms in women, atrioventricular blockade of high degree, AF or Atrial flutter, ventricular extrasystoles of high gradations. All the above mentioned require the appointment of additional examination.
