I had cardioversion for A fib in September 2011. I am doing fine on the a Fib now under control, but have had voice loss since that procedure. It is a very handicapping to my business life. My cardiologist says he has never seen this happen. My regular doctor and other docs are also all puzzled. I have had nuerology testing (needle test into vocal folds) and left vocal fold indicated some nerve damage. I have worked with ENT Doctor scoped down my nose twice and voice specialist also looking at the voice machinery and all looks like should work. I have slight noticable iritation in my left side of throat that is not changing. I am concerned as such a long recovery from side affect of common procedure. Can anyone share experience or advise what my next step to fix? thank you!
