I am a 58 y/o male. I was found to have AF after minor knee surgery caused a DVT and PE clot. I am currently on Apaxiban and Metaprolol. I am waiting to have defibrillation treatment ( sorry i dont know the technical names) but this cant be done till after the clots have cleared up, hopefully in about 3 more months, its already been 6 months. I read with interest that people can tell when they are in and out of AF, i havent noticed, i always seem to be short of breath when working or exercising, could i always be in AF? What is the success rate of a single Defibrillation treatment? Could this be an ongoing issue? Its hard sometimes to get answers off the specialists.
