I was put on amiodorone after I got afib after the lung surgery. Seems it's very helpful for afib. And the scientists discovered that by accident. Took it in pill form for about three months and then got off it - sounded like it could turn your skin blue - not to scare anybody! I always find it helpful to read up on these drugs for side effects. Now take a betablocker - attenolol for it and it keeps my blood pressure down a bit.
