I had a bout of Afib back in May and was at that time switched from a Beta Blocker to a Calcium Channel Blocker. (I had a bout of Afib 2 years prior as well). Since then I had a really bad flair up of PVC's that landed me in the ER last week. I went for a follow up with my GP this past Tuesday and he added 12.5mgs of Metoprolol (sp) a day along with my 120mgs of Cartia XT 2 times a day. The first day it was WONDERFUL, not one PVC then yesterday they flared up again. My question is, is there a time frame for your body to adjust before this combo of meds will begin to work effectively for the PVC's? When I was on the beta blocker before (50mgs once a day) I didn't ever hardly have any PVC's. I have 2 small children and I'm afraid to even MOVE when these things flare up! I'm really really hoping that I just need to give the medication time! Thank you in advance for your help.
