Hello Zacklucy, I have had A-fib for probably 20 years and have been on Verapamil for almost the whole time. I'm also on Losartan + HCTZ (100 MG + 25 mg). I've been on the highest dosage of Verapamil for the last few years (240 MG, 2 pills q evening). About a year ago I finally agreed to take Xarelto 15 MG (due to a family history). Overall, my A-fib rarely acts up. If it does, I can take a half a pill plus .5 of Ativan and it calms down.
I've had no problems with the Losartan. And I have an Echo done once a year.
So, sometimes it just takes some experimenting a bit with the meds (your doctor, that is) to find the right med or combination of meds to get it right.
