My Husband Has A Fib After An Aortic Valve Replacement.
My husband has a fib after an aortic valve replacement. I know this is fairly common, but his a fib goes from 160 to 45 sometimes. is this something I should be concerned about. He just got zapped back to regular heartbeat last week and went to cardiac rehab for first time today and is back to high a fib number. Is this a big concern?
