If you don't wear the apparatus, you get no therapy...period. A CPAP machine is designed to help you to splint your airway while you have lost tone and are unconscious, sleeping. It is NOT designed to ameliorate other problems. However, it could help to stave off the evolution to more dangerous states if it delivers the proper therapy to you reliably, night-after-night. For example, I have atrial fibrillation. No diagnostics suggested I ought to have AF until the last one my cardiologist recommended to me, which was the polysomnography over night. Once it was established that I had severe apnea, my cardiologist said, and I quote, "Well, I guess we know why you developed atrial fibrillation.' My heart was cranky, and irritated, because it was always dealing with adrenalin and the higher, non-restful, rate due to its inherent programming to run faster when I ran low on oxygen. It could never rest!!

BTW, you need a better doctor. Anyone who blows off someone in your condition with, 'The only one I know isn't taking any patients.......sssssssooooooooooo.......' is as useless as female chest appendages on a bull.

Also, do you really need a referral? Could you not call a local electrophysiologist and ask that person to see you...urgently? He/she will want tests, which will mean a delay, but at least you'll have that much going on toward an eventual bit of...you know...HELP!
