Thank for such a helpful reply! The discussion you linked had great input.

I’ve known for 2.5 yrs, but haven’t had symptoms until recently. No obstruction and no meds, but yes I have good and bad days.

I’m really interested in understanding if there’s a safe max heart rate to serve as some sort to guide so will keep looking into that. My cardiologist is one of those who says “go live life” but I have a young daughter and when I think of her, that advice is way to vague!

Thanks again for the info 🙂
