EKG
We offer in-office EKG screenings. An EKG, or electrocardiogram, is a quick, painless test that measures the heart’s electrical activity. In Florida, student athletes are required to have a sports physical completed on the EL2 form before participating in high school sports.
Every EKG is interpreted by our providers using the International Criteria for Electrocardiographic Interpretation in Athletes—the current international standard developed specifically for athletic hearts. These guidelines help identify heart conditions that may increase the risk of sudden cardiac arrest while reducing unnecessary referrals for normal athletic heart changes.
