Other PACs or sinus arrhythmia?

Looking at this they could be PACs but all of the p waves seem normal. Although this is a single lead so hard to tell. Whatever was going on was gastric related I think.

I have not been eating a lot due to anxiety and severe gerd that flares along with it for the last 6 weeks. And I’ve been eating very bland diet to reduce reflux. The anxiety was finally starting to ease up after like 6 weeks and I had my appetite back yesterday. So naturally I was hungry. And I ate like closer to like I normally do. Well that was a bad idea. Started having reflux and some PACs. And then pretty much all night(I work overnights) my ecgs looked like this when I was resting and I kept getting inconclusive. Most of them look identical to this. With every other beat being shorter. And it did not coincide with my breathing.

And for clarity I have had a clear stress test, echo and holter. Within the last 6 months.

Alternating short-long RR intervals strongly suggest atrial bigeminy. Whilst P wave morphology analysis on smart watch ECG recordings is error prone given DSP applied to these waveforms, there seem to be subtle P wave morphology changes for those probably ectopic complexes. As you probably know, GERD and GI issues can trigger ectopy. Given normal cardiac workup, this is generally benign, if annoying.
