Syncope and presyncope are relatively common presentations among athletes. The distinction between post-exercise and during-exercise syncope is critically important. While the great majority of these episodes occur just after exercise and are benign, syncope can be an indication of serious underlying cardiovascular disease if it occurs during exercise. Syncope presents a challenging differential diagnosis, as well as a daunting array of diagnostic tests and advanced imaging strategies. Sequencing a proper evaluation, and deciding who requires consultation and restriction, can be difficult for the medical provider. We present a systematic approach that assists the sports physician in arriving at a diagnosis and organizing an initial management strategy.

Clinician ECG interpretation according to the ESC interpretation criteria appears to demonstrate limited reliability and validity. Before widespread adoption of ECG for PPE of U.S. athletes, further research of training focused on improved reliability and validity of clinician ECG interpretation is warranted.

This pilot study reveals a low level of agreement between physicians regarding which athletes with an abnormal examination deserved further testing. It challenges the standard of care and questions whether there is a need for improved technologies or improved training in cardiovascular clinical assessment.
