I'm a 31 year old male. Generally healthy although I suffer from health anxiety.

4 weeks ago I've got a weird feeling in my chest and I measured my heart rate in my neck. My heart rhythm was all over the place. Several weirdly timed beats in a row. I coughed and it stopped. It lasted like 5-7 seconds.

A bit later I had the exact same experience two more times. 2 days ago also once and last night also once.

I can only describe it as 'bubbles' popping in my chest. Like a mini whirlpool in my chest where bubbles are reaching the surface. Another description could be corn popping to popcorn in your chest, in combination with a general weird feeling. 'Fluttering' is I think a common term here and that could very well be it.

It only happens when I lie down or in rest. Not when standing up and walking or exercising. I've had this a couple of times in my life now, but this month it is more than ever.

First my big question is, are these PVC's or can they be short bouts of Atrial Fibrillation?

My stomach and intestines are also acting up lately. Lot's of gas and air trapped in my gut. One burst of flutters in my heart rate was literally timed with gas bubbles in my abdomen. The one I had last night wasn't.

I went to the doc 2 days ago. Had an EKG (10 seconds) and came back fine. She does not believe in a connection between the gut problems and the arrhythmia's.
She thinks the arrhythmia's are harmless and can act up more with stress.

I will be put on a 7 day holter monitor later to rule things out, but the first possibility for this is in 3 weeks unfortunately.

So nothing to do for me at this moment... But I'm really worried so any answer would greatly help me. As you can imagine, I'm losing sleep over this because they happen at night.

Does this sound like PVC / PAC to you? It is not 'one' heart beat skipping or missing, but several in a row. Could they be short bursts of aFib? Is that even possible?
And why would they act up more now and only during the night?

Any help is greatly appreciated. Take care everyone.
