I am just asking this out of interest. When I was diagnosed with AF I was informed that the danger of AF is that a clot may form in the left atrium . This is caused by the irregular heartbeat/very fast heartbeat as the blood pools in the atrium and may clot. Now I read on this website often that people have had an ablation and/or been successfully treated with medications and have not had an attack for several years and so the only medication they take is an anticoagulant. Surely it must follow that if there are no AF attacks then there is no danger of the blood pooling why take an anticoagulant? I am aware that there may have been some damage to the structure of the heart but if this is not the case and there are no attacks why anticoagulation?
