Granny, Glad your chickens are doing better. Sorry to hear things aren't going well with your husband. My Mom went through the A-fib for a while. The first time she was controlled with medication and the second episode did not respond to medications and she went into congestive heart failure.They had to cardio convert her and then her heart went back into a regular rhythm. Eventually she started having more and more episodes of A-fib, which sent her back into heart failure. She also had a lot of fluid in her legs and also her abdomen due to the heart not pumping efficiently, which sent her into failure. She eventually saw another cardiologist, who placed a pacemaker and that did the trick. Hope they'll soon find a treatment that will work for you husband.
