Sometimes when I sleep it feels like if i don't wake up I'm going to die so i check my pulse the last time and it was 43 i am 5'2 and 275 is that normal i don't know if I'm wording it right but it feel like I'm going to pass out or something and I'm already sleep
Some medications can do that. PCP should be able to handle that. If not, then check with cardiology. Specifically Beta blockers or anything sedating can cause the heart to slow down.
