My son passed out for the first time in Feb. at baseball practice he was taking by ambulance to ER all test were normal followed up with cardiologists and echocardiogram was normal, this past Tuesday while at football practice he had another episode never passed out just felt dizzy and light headed his trainer suggested to get his sugar checked we did and it was fine his pediatrician thought he might of been dehydrated and wanted us to follow up with cardiologist. We go in the morning for that appt. just wondering if anyone else ever experienced this kind of stuff.
