The conversation between human and AI assistant.
[|Human|] ok this has me a bit scared. i am 46 and use a cpap machine everything seemed fine until about 3 weeks ago. I just was getting very anxious and stressed out and literally broke down crying and took myself to the emergency room, my chest had been hurting for a while. I have noticed since then that when i lay down to sleep that my heart seems to be be beating differently or at least feels this way. My lungs seem full of fluid and I am NOT sleeping super well. I go to bed quite early, wear the mask and am often up at 2 and cannot get back to sleeep wearing the mask. Why so sudden? how scared should I be, I am tired all the time, but not falling asleep at the wheel or anything. I am thinking that something has really changed and that I am suffering from sleep deprivation
[|AI|]  Hi, Is this a fast heart or irregular heartbeat, is there a shortness of breath associated? There is some problem probably in heart, likely atrial fibrillation which is common in patients like you. From your description or some other which is causing sleep deprivation and all secondary problems. So you should get yourself examined and one ECG should be done. If needed holder monitoring should also be done. Hope I have answered your query. Let me know if I can assist you further.
