Various degrees of atrioventricular blocks have been described in endurance athletes. First Degree Blocks and Second Degree Mobitz Type- 1 are a common finding. However second degree Mobitz type -2 and third degree blocks are pretty rare and should be considered pathological The athletic hea syndrome - Spos Cardiology: From Diagnosis to Clinical Management Springer 2012 18, 19 Benign findings Physical exam Grades 1 and 2 systolic ejection murmurs Split S2 S3 or S4 ECG changes Sinus arrhythmia Sinus bradycardia First-degree hea block Second-degree hea block Mobitz 1 Junctional escape beats Voltage criteria for hyperophy High QRS Voltage Early repolarization Incomplete right bundle branch block P wave increases in amplitude and duration Tall peaked T Waves T-wave flattening for inversion that normalizes with exercise Prominent U waves Pathologic findings Physical exam Systolic murmurs at the lower sternal border augmented by Valsalva and decreased with squatting Diastolic murmurs ECG changes Down-sloping ST-segment depression ST elevation with broad T waves Significant Q waves anterior or inferior pattern Delta waves Wolff-Parkinson-white Second-degree hea block Mobitz 2 Third-degree hea block Prolonged QTC interval LVH with ST-T wave strain pattern These findings assume an asymptomatic athlete.
