[|Human|] hi What does it mean... I will to to bed 10pm and  sleep through the night maybe get up for the bathroom once or twice. I start work at seven thirty am so I would get up at six thirty. so i got to bed and every morning i wake up and  by just opening  my eyes and all of a sudden my heart is beating fast, then i will do some breathing and it goes back to normal. what does this mean and what should i do. I had  a sleep apnea test and that was fine but i;m wondering if i need to get another.
[|AI|]  Hi, when you're about to wake up, your sympathetic system is most active just before that. that's the reason a person may feel fast beat while waking up.  Moreover, in REM sleep your heart rate is faster, and we have Chat Doctor. don't worry. I suggest you take an ECG just to have a baseline. And do yoga and meditation.  If it's causing you too much trouble, then consult a cardiologist.24 hrs holder or stress test may be advised.
