I am a 31 yr old male, and I went into afib a few months ago. the bout only lasted for about 24 hrs and i have not gone into afib since. over the last few weeks my heart has been fluttering often accompanied by tightness of chest and numbness in my left arm. I have checked out with a clean bill of health with my doctors, and I am confused. I believe I found the commom denomonator but I am not sure if these issues can be linked. I am constantly having back issues, and about 2 years ago i went to the chiropractor to find out my spine looks like that of some one who jumps out of planes for a living and i have to go in every so often to get adjusted and treated for sciatica. my afib and flutters only happen after I have aggrivated my back and nerves. my question is: can these be linked, and are your nerves part of the same electrical system that controls your hearts rhythm?
