@vbpets Exactly. You must have a solid grasp of your own real risk. It's always strictly a person choice, but the wisest of us learn all about our risk of thromboembolism for us as individuals with our medical history before arguing or simply stopping with a unilateral decision. It is because so many AF patients don't have symptoms that they can't possibly know when their last AF episode was or even if they're currently (still) fibrillating. They would have to use a wearable or blood pressure monitor with graphic ECG display to both count beats and to visually assess the waveform of the PQRST.
