My husband has his first AFIB attack on 4/11/14 and since then has had three attacks. I feel it s because he has Sleep Apnea but he tried a sleep study and/or clinic and it didn t go very well. He is a little clostrophobic as well as a really light sleeper. Needless to say with 25 wires hooked to him, oxygen, and the finger clothes pin oxygen monitor on him and then told to go to sleep. He laid there for an hour and thought it seemed like forever -- he freaked out when they hooked him up to all of the machines and couldn t sleep & had to leave. He has had an echo gram and stress test and blood work and we meet with his cardologist next week. He told me the only way he could do the sleep test again is if he was sedate and/or knocked out. Is there any other way to test for sleep apnea other than to go to a paper thin walled small room and be hooked up to 25 wires and three different machines and then try to sleep while someone is watching you through a camera as well? He said the three times he has had his AFIB attacks he has slept in his chair before going to work and has woke up at least 10 times at one time because he was not breathing. Since then he has laid down on the floor to nap before work and that has seem to help not cut off his air passage as much by laying down on the floor. Can a doctor recommend a Sleep apnea machine without all of the results from a sleep study test?
