Question about drug use & rapid heart beat
I know someone who uses meth, prescription pain killers and alcohol regularly. On a typical day, he'll get up and do a couple lines of meth, then in the evening he'll drink a few beers and then about midnight, if he wants to sleep, he'll take an oxy or a vicodin or a hydro or some other kind of prescription pain killer to come down off the meth so he can fall asleep. Oh, and he's also a pot smoker, so he'll sometimes drink beer, smoke some pot, then take a pill or 2 at night. If he doesn't mind staying up, he won't do the pills or beer and just stay up until he can fall asleep, usually around 5 am.
I've noticed that while he's sleeping, his heart beats really fast! I mean, his heart beats faster while he's asleep than mine does after I've worked out. It's really, really fast. Fast enough that it used to scare me, because I didn't know if it was bad enough to cause some kind of damage or even a heart attack.
So my question is, does anyone know if this rapid heart beat is likely to be caused by the drug abuse? I would guess it is, but I'm not 100% sure. And also, how much damage could this be doing? I have palpitations that come and go and my doctor told me that they could cause arrythmia (incidentally, I don't use any illegal drugs...I have health issues). If occasional palpitations can potentially cause a heart attack, what about this rapid heart beat? I can't imagine how fast it must beat when he's up and moving around if it beats this fast while he's asleep! I believe he could eventually kill himself with the effects of this dangerous drug cocktail.
Any answers are appreciated.
