It's really good to see that you're starting to challenge your health anxiety a little. It's a slow process to accept the ectopics and keep reminding yourself they won't bring you harm, but you will gradually make progress little by little and eventually win that battle!

Yes, the Apple Watch is one such device that will count a PAC but not a PVC as a beat when taking an ECG recording and reporting your heart rate.

(Slightly off topic, but I had a quick flick through your account and saw you've started Pregabalin. How's it going in terms of the mental health? After trying LOADS of meds unsuccessfully myself that was the one I finally had a breakthrough moment with, and saw my anxiety improve with it as I upped the dosage. Hopefully you're having similar luck with it?)
