My 15 year old son fainted. Blood sugar -86, EKG- vent rate-96, RR Interval-622, PR Int-128, QRS Duration-92, QT Int-336, QTc Int-399, QT Dispersion- 18, P-R-T axis-73 78 59. Dr said ECG was normal but it does have unusual RSR in V1 and V2. What does that mean ? Is this dangerous? He did not eat or drink that day and one other day he felt faint but squatted and then sat in cooled car and drank a bottle of water, then felt better and finished hitting some golf balls . But once again he did not eat or drink. Could this be why he felt faint?He only has fainted on time. He was cold ,clammy and his head started to sweat after passing out
