Of course I'll give my full medical history, I'm not stupid/naive enough to not do so. Nevertheless, the breathing has nothing to do with it (apparently there are many asthmatic pilots, even with Ventolin allowed, which won't even be my case, as I said my asthma is VERY mild), and many times I've been in pitiful states and my heart didn't do anything. So the conditions I've given are arbitrary and may even have no direct link. The doctor I saw today said that it could possibly be linked also with my horrible eating habits.
Anyway, I imagine that if my heart really does have a problem, the medical test will point it out...
