USCG Position on A-Fib

Recently Diagnosed with A-Fib. Have USCG physical due shortly and worried about the CG position on this condition. Not a high risk for stroke, and have letter from Dr indicating that the condition and medication is not a hinderance to job performance. Anyone deal with this before? I am hoping it is as easy as getting a medical waiver, but don’t want to find out the hard way that I need a new career.
