I am 76 years old with pacemaker for low heart rate. Went into AF full time. Cannot take blood thinners due to minor lung condition which causes me to cough up blood when on thinners. This is due to some inflamed blood vessels. Atenolol and Fleckinide worked for 4 years. Still on Atenolol but off fleckinide. Had cardio version that worked for 5 days. Was on amiodorane for 6 days but had some side effects. Am scheduled for cardio version and hospital admission for purpose of testing dofetilide.
