My doc is switching me from multaq to amiodorane for 1 month after a second ablation for a-fib. I was having breathing problems especially in the mornng. I'm on lisinopril, metropolol, warfarin, L-thyroxine, chlorthalidone (12.5 1x daily), calcium, magnesium, co-Q10, D-3, B-12 and fish oil. Do you see any problems?
