I have been experiencing a strange thing over the last 2 years

This answer was rated:

I have been experiencing a strange thing over the last 2 years every couple of weeks. I wake up always within 1 hour of falling asleep and feel as if I'm dying then my heart starts racing and pounding. I sit up and it lasts for about a minute then it slows. it is frightening at the time and very puzzling. Only happens in sleep and always within 1 hour.
Have you heard if this.
Customer: replied 2 years ago.
I is not sleep apnoea and it is not anxiety. I am awoken with a feeling as if my heart is not beating properly and I feel as if I'm dying then it goes into a fast forceful heartbeat. I don't gasp for air I am calm when I wake up, just feeling weird.
My feeling is that something happens within my body within half hour of falling asleep and my heart is reacting to it.
Have you had a holter monitor?
Customer: replied 2 years ago.
Yes I've had one for 24 hours but nothing happened during that time.
Did they consider a longer monitored period of time? Anxiety a possibility?
Customer: replied 2 years ago.
No but perhaps that is the only way to capture it. I don't think it's anxiety as its specific to a particular time. I don't get it during the day and always after having been asleep about half an hour! I have a sensitive heart and sometimes get flutters and occasional svt but ecg's have always come back ok. It's very puzzling.

Does the body cheat rate, bp etc change after being asleep for a short time? Perhaps it's something to do with this?
This is actually a pretty common complaint. I have heard it many timesIt is generally benignA longer holter is the only way to prove it

I will ask to have a longer monitor period. Does it have a name? Do you know what causes it?
event monitorIt is generally a string of PVCs that triggers the waking response
Customer: replied 2 years ago.
What's a PVC?
it is a benign extra beat
Customer: replied 2 years ago.
So is it possible I'm getting a run if PVC and then I wake up and then the heart is overcompensating by beating strongly
Customer: replied 2 years ago.
is this dangerous? I'm due to go away on holiday and worried it happens when I'm away
It is not dangerous in 99.9% of cases
Customer: replied 2 years ago.
Thank you. I will get a longer holter monitor organised just to confirm that this is what is happening.
sounds good
Customer: replied 2 years ago.
I just remembered to ask something else. Will PVC's be more likely during night when I'm on my side? I try to stay on my back as had a few on my side but not sure if coincidence.
Customer: replied 2 years ago.
Yes to coincidence or yes to worse on my side?
yes it is generally worse on your side
