I recently was cardioconverted on an outpatient basis. I was given very little post instruction except follow up visits. In 2012 I had AF for the first time and I was converted and admitted into the hospital for 4 days in which I returned to AF and was converted again. It wasn't until Oct 2017 that I returned to AF and had my latest shock conversion. This time I am extremely short of breath, and hardly walk more than 6 feet without exhaustion and have to rest. Doctors don't seem to believe me or understand what I'm saying is TOTAL truth, they seem to think I'm acting or something. I was wondering if light exercise like walking would help build my strength back or would it be harmful? I was an electrician in a very physical lifestyle before any of this happened. Now I wouldn't last 15 minutes on the job. Thanks for all replies. I am also using amiodorone.
