A 42-year-old healthy man collapsed suddenly in the street while walking. The patient received 2 minutes of basic life support until an automatic external defibrillator was brought and detected ventricular fibrillation (VF), which was successfully terminated by a single shock. The patient regained consciousness and was transferred to the hospital.

The patient’s physical examination was normal with no neurologic deficit. Blood pressure was 147/102 mmHg. Brain computed tomography showed normal findings. The first troponin I measurement within 1 hour of the event was in the normal range (19.6 ng/L, normal < 20 ng/L) and rose to 99.9 ng/L after 3 hours.

Electrocardiography abnormalities are a common finding in athletes. To facilitate the differentiation of physiological adaptation versus pathological remodeling, a series of guidelines has emerged in the past decade that attempt to improve specificity while maintaining a high sensitivity. Recently, T wave inversion in the athletic population gained more attention, resulting in accelerated research leading to novel findings not yet integrated into clinical practice. We aim to simplify the knowledge to date and integrate it into one easy to use practical flowchart.
