Went to hospital last Sunday by ambulance. Husband found me out and not breathing. Breathing tube, stomach pumped and ended up in icu and then hospital room. All I remember was having a headache. Have afib and had abliation and cardioversion back in March. All started last December with afib. They think I had a bad sinus, asthma, or lung infection. Am wheezing, have some voice box damage and heart rate and bp very high. My rate and bp were good before all this. Now I am back to square one. Cardiologist said just watch it. Not reassuring. Has anyone had an experience with passing out? Never happened to me before. Now I am frightened to be alone. Thanks.
