I've had that erractic beat happen to me. I can feel it, beat fast, then slow down, then beat fast. I've been checked by cardio, and by primary and they say no problem. But I have no underlying lung/heart conditions. He really should get it checked out. It is probably nothing serious, but you never know.
My biggest issue is caffiene. If I drink too much I get way out of whack. But my doc keeps stressing that it is not dangerous to me. Some medications can cause an irregular heart beat too. Just a thought.
I'm not procrastinating----I'm still doing yesterday!!!!
I have no medical training, any medical opinions expressed in my posts are just that....opinions.
