[|Human|] when I was 13 i was playing basketball. then all of a sudden i was seeing spots, felt faint and I blacked out for about a minute. my heart was beating so fast. and it didnt slow down for a long time. And it still happens to this day. whats wrong with me?
[|AI|]  Hi, This can be arrhythmia like PSV or atrial fibrillation, where your heart rate suddenly goes up and BP falls. You will need evaluation like ECG, thyroid test and holder monitoring. You should also get one hemoglobin levels done. So visit nearby cardiologist for this investigation. Also, to abort such episodes you should try to cough hard. Is there any stress or anxiety associated. Till the time your evaluation is complete, you can ask your local doctor for tab collar. Hope I have answered your query. Let me know if I can assist you further.
