The fourth annual Heart of a Champion Day athletic screening for high school student athletes attending Charlotte-Mecklenburg Schools (CMS) will be held at Carolinas College of Health Sciences, 1200 Blythe Blvd., Saturday, June 4, from 9:00 a.m. to 1:00 p.m. More than 400 medical volunteers will screen nearly 2,000 high school students who have pre-registered. Sponsors are CMS, CMC, CMC Sports Medicine, Levine Children’s Hospital, Sanger Heart & Vascular Institute and OrthoCarolina. Sanger, eCardio and McKesson are providing financial support. Screenings will include an electrocardiogram and echocardiogram to check for heart abnormalities that can lead to sudden death. For the first time this year, students will be given a baseline balance test that will help diagnose future concussions should they occur. Also included will be general medical and orthopedic screenings. Video/photographs of the screenings will be permitted and interviews with medical volunteers and students will be available.
