Abstract :

Normal ECG Findings: Increased QRS voltage for LVH or RVH, Incomplete RBBB, Early repolarization/ST segment Sinus bradycardia or arrhythmia, Ectopic atrial or junctional rhythm, 1Ë? AV block, Mobitz Type I 2Ë? AV block. Borderline ECG Findings: Left axis deviation, Left atrial enlargement (>42 mm), Right axis deviation, Right atrial enlargement Complete RBBB. Abnormal ECG Findings: T wave inversion, ST segment depression, Pathologic Q waves Complete LBBB, QRS ≥ 140 ms duration, Epsilon wave, Ventricular preexcitation, Prolonged QT interval, Brugada Type 1 pattern Profound sinus bradycardia < 30 bpm, PR interval ≥ 400 ms, Mobitz Type II 2Ë? AV block, 3Ë? AV block, >2 PVCs per 10 s tracing (>12/min), Atrial tachyarrhythmias, Ventricular arrhythmias. Summary: • ECG interpretation in athletes has evolved to help distinguish physiologic ECG findings from pathologic ECG findings. • Some form of T-wave abnormality (inferior, anterior, or lateral) accounted for 35% of ECGS which were not normal but not pathological. • Other common themes included the application of the IC definition of IVCD (≥140ms), sinus bradycardia (<40bpm), and right axis deviation (≥120 degrees). IC=International criteria.
