Best Practice Case Studies-Case 116 Asset 3 ECG Interpretation in Athletes

Video Transcription

Video Summary

The session featured Dr. John Dresner presenting on ECG interpretation in athletes. He explained why ECG screening matters, emphasizing that sudden cardiac death accounts for most sports-related fatalities and that ECG can help detect conditions such as cardiomyopathy, ion channel disorders, and pre-excitation.<br /><br />Dr. Dresner reviewed the evolution of athlete ECG standards, from early European criteria to the Seattle, Refined, and current International Criteria. The International Criteria classify ECG findings as normal, borderline, or abnormal, with clear guidance for when additional evaluation is needed. He stressed that borderline findings are only concerning when two or more are present.<br /><br />He then outlined his practical six-step approach to reading athlete ECGs: assess precordial and limb leads for major abnormalities, evaluate QRS morphology, check axis and atrial enlargement, review rhythm, and estimate the QT interval. He highlighted several normal athletic variants, including high voltage LVH, early repolarization, incomplete right bundle branch block, black athlete repolarization patterns, and juvenile T-wave inversion in athletes under 16.<br /><br />Abnormal findings discussed included lateral or inferolateral T-wave inversion, ST depression, pathologic Q waves, Wolff-Parkinson-White, complete bundle branch block with marked QRS prolongation, and prolonged QTc. He emphasized that lateral/inferolateral T-wave inversion often requires cardiac MRI, and that athletes with marked ECG abnormalities but normal imaging need serial follow-up.<br /><br />He also compared ECG screening with history and physical exam, showing ECG outperforms the AHA 14-point screen in detecting occult cardiac disease.<br /><br />Finally, Dr. Dresner addressed COVID-19 cardiac concerns, noting that symptoms and illness severity should guide evaluation, and reviewed ECG findings suggestive of myocarditis.
