A Sudden jump (beat)of heart

I would like to know if someone else have the same symtom as mine, or is this serious or normal?

Sometimes just as I get to sleep, I was waken up by a sudden 'jump' of heart and scared to sit up immediately and feel a sudden panic and put my hand to chest. At that moment I feel the heart may jump out of breast and also feel no air in that second.This only lasts one second.

Most happen at the time I just get to sleep. But recently sometimes in the day it happens too.

For example when I sit at my desk and working and I suddenly feel an experience of the sudden 'jump' or 'strong beat'.

Recently it happens about twice a day.

I had this since a year ago, and had all kinds of heart test and exam, stress test, ERG, 48 hours host-moniter, etc, doctor said heart is normal and cannot find out what's wrong with me.

So I decided a year ago to live with it, and at that time I also consider it may be anxiety or stress, but now I work in a pretty relax enviroment, it happens too.

So I would like to find out if others have the same syptom, and what is going on with me or my heart?

Thank you.

Why the 2 doctors I saw didn't say anything? Just said no heart problem, And make me so puzzled and confused.

I have a  couple of more questions,

But when you said " If you've had the work-up you said, your heart is in good shape and you should treat these as an annoying inconvenience"

What do you mean by work-up? English is my second language, not familiar with this word.

Also when I see the word contraction I feel the symptom is quite like a sudden contraction.

What caused PVC, is it possible related with food? ( a year ago I also had GI exams, doctor ruled out GI problem), but will food affect PVC? I don't have this symptom 2 years ago.

I also a little bit animia due to uterus fibroid, could animia cause PVC?

Thank you

I did see Cardiologist and GI doctor and did all kinds of tests.

No doctor can give me an explanation. So that's why I get to the forum to see if others have the symtom,

when you say, "When someone suffers from PVC's it is usually a pretty constant occurance for them.  Not just one beat then it is gone. "

My symptom is it happens in just a split second, then it's gone.

so I would like to know from the forum how others think.

Thank you.
