[|Human|] Its happened 3 times now ill be out running around doing whatever with friends and all of a sudden ill get light headed and weak and wont be able to feel my pulse or heartbeat for a little while. Im 16 and have never smoked or done any drugs. whats up with that?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of heart block is more. In this, due to conduction block, impulse can not travel from atria to ventricle and hence heart skips that beat. So blood supply is also impaired. If this episode stays long, blood supply to the body is reduced for long time and hence you feel weakness, dizziness, light headdress etc. It is commonly seen in young individuals, so we should first rule out heart block in your case. So better to consult cardiologist and get done ECG, 2d echo and Holder monitoring (24 hour continuous monitoring of ECG) for the diagnosis of heart block. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
