Scattered heart rate

I’m in the process of getting officially diagnosed with POTS or some form of dysautonomia. I was going through my Apple Watch data, and I noticed that every once in a while during the day (while I’m awake), my heart rate will dip below 60, sometimes even into the high 40s. However, it’s only for a minute at most.

Just now I caught it happening live (lol), I stood up from sitting, felt off, checked my HR, and saw it had dropped to 57… then jumped up to 110 within the same minute. It’s actually been a pretty decent day symptom-wise, and my HR hasn’t gone above 120 all day.

Is this kind of dip/spike pattern normal with POTS? Or could it point more toward another type of dysautonomia? I always thought POTS was mostly about the fast heart rate, not random bradycardia too.
