The GP probably won't know about diving/freediving-related injuries. But, it may still be of value and just tell your GP you have chest pain upon exercise and then tell him/her you want to rule out cardiac problems.

All the best.

Well, last year I had complete cardiac evaluation. One part of it was 24 hour heart monitoring which discovered minor abnormality called supraventricular ectopy-it is iregular heartbeat. It occures in 0,1% of all heart actions in monitored time so it was classified as minor, and final result of a tests was "tests show no sign of heart desise".
I mentioned my freediving activities to a cardiologist and ask him is it ok to continue with that, and he said no problem. But I wasn' convinced, my feeling was that he was not completly sure what I was talking about when I mentioned freediving, what are effects of that on healthy body, and even more on unhealthy one. So, I think visiting a specialist on diving medicine will be needed.
I must say that it wasn't my attention to underastimate any medical worker in any way.
