I have minor regurgitation and have had 2 bouts of a-fib.  I also have mitral valve prolapse.  Is a-fib common with the minor regurgitation and or mitral valve prolapse.  I have been under much stress also and overweight and out of shape.  Could this have caused my nervous system to over react as is what happens with mitral valve prolapse patients.

Summarized question: Can overweight cause mitral valve prolapse?
