Hello Toniaw.
I am 57, male and I recently wore a Zio monitor for 6 days. I have been suffering with PACs and PVCs for 20 years and in the past four months, they have become much worse. Three ER trips and I have been working with an electrophysiologist. Now, when I wore the Zio in 2021, below are my results. My cardiologist said that everything was normal and SVTS do happen and in the absence of structural heart disease, there is nothing to worry about.
They have also told me that even having PAC burden of 10% is okay. Sadly, I am one of the few who can feel almost everyone of them and they are very scary. BUT....again, my cardio keeps telling me that I am fine!

I still get the occasional SVT where my heart will accelerate for about 2-3 seconds and then get back to normal. My cardio told me not to worry about, but it happens maybe once a month. They are scary, but again, the cardio told me not to worry about it.

2 Supraventricular Tachycardia runs occurred, the run with the fastest
interval lasting 5 beats with a max rate of 120 bpm, the longest lasting 5
beats with an avg rate of 93 bpm. Supraventricular Tachycardia was detected
within +/- 45 seconds of symptomatic patient event(s).
