I am no expert & of course you should research your own case as much as you can but
I have had PSVT for 30 years now on & off & also now have many PVC's & PAC's I am 66
I am in very good health otherwise with a strong heart that is structurally fine. I take no meds like Cholesterol,BP etc as I'm all good there
I do sometimes take low dose aspirin just because it is simple & as someone once told me makes a slippery heart ????
One resource you may like to look at is this YouTube channel called York Cardiologist
He has a ton of videos on various Afib, PSVT. SVT. PVC's etc etc & is very informative
Good Luck
