I go into AFIB about every other week. Very painful for me. Pain in chest, arm, dizziness, sweats, usually head hurts too. I had triple bypass in 1998 and AFIB began couple of years ago. I usually would have to be admitted and put on meds. I've had a cardioversion and one year ago had an ablation. AFIB has continued and is getting worse. I am on blood thinners. My doctor has given me two options, Tikosyon or another ablation. My first ablation took 6-7 hours under anesthesia and another 6 hours lying on back. Caused severe back pain for a long period of time and no relief from AFIB. With the Tikosyon option I would be hospitalized for 3-4 days to determine dosage. If anyone is on this medication I would love to know how it is working for you. I am leaning towards this option.
