My 17 year old son woke up this morning with severe chest pain and pain in his left arm. We went to our local walk in centre where they did an ECG, the doctor told us there are couple of things on the ECG that could be perfectly normal or they could indicate a problem. He's given my son painkillers and gaviscon and if the pain doesn't stop in 2/3 hours we have to take him to A&E and give them the ECG report. It's a long shot I know but I wondered if anyone could tell me what is showing up on the ECG. Thank you.
