Hey, for a guy, is it too low if his heart beat is 48 bpm? He s been constantly dizzy and couldn t see for a couple of minutes (like complete blackness). He thinks the dizziness has to do with his migraines. He s constantly shaking. I m scared if there s something wrong...48bpm is too slow right? (he not athletic..well, not really...not recently anyway) And what are things (beside medications) that can help bring your heartbeat up? Like, are there types of food that could help..maybe? any advice is welcomed =) thanks... Additional Info: his blood pressure is QUITE high...i m not sure what it is, but it really really high (or so he says) sorry i didn t mention this before...^^
