NEW CALIFORNIA CHAPTER SPORTS CARDIOLOGY AND EXERCISE HEALTH COMMITTEE
The American College of Cardiology’s California Chapter has established a Sports Cardiology and Exercise Health Committee in response to the growing need for evidence-based, standardized, comprehensive care for athletes. The committee aims to serve as a resource for consultative cardiovascular assessment of highly active individuals as well as a home for educational tools to aid in their assessment and management.

ECG'S IN THE ATHLETIC POPULATION
The present document will provide a succinct overview of the interpretation of the electrocardiogram (ECG) in the athletic population by providing select resources for a more comprehensive understanding of ECG changes occurring in athletes, supported by a few examples of abnormal findings.

RESOURCES FOR PROVIDERS
This document does not serve to support or refute the case for pre-participation screening with an ECG, but rather as a resource to help those providers whenever they are faced with analyzing an athlete’s ECG, including team physicians, family medicine, sports medicine, cardiology, athletic trainers and others caring for athletic individuals.

SELECT ECG INTERPRETATION RESOURCES
1. ECGs provided in this document with brief description. ECGs obtained from Dr. Vic Froelicher.
2. “International recommendations for ECG in the athlete” provides tables and figures that clearly delineate normal and abnormal ECG findings (Figure 1), definitions of ECG findings (Table 1) and evaluation suggested in the setting of these ECG findings (Table 2).

Guidelines from International Recommendations for Electrocardiographic Interpretation in Athletes


In the JACC article and the slideshow below are tables and figures that clearly delineate normal and abnormal ECG findings (Figure 1), definitions of ECG findings (Table 1) and evaluation suggested in the setting of these ECG findings (Table 2).
