It is clinically understood and documented that when a patent is experiencing a prolonged atrial fibrillation (AF) episode of about 48 hours or longer, delivering an electrical countershock to the atrium could cause the patient to have a stroke under certain circumstances. A cardiac rhythm management device that delivers an atrial countershock to interrupt the AF should not be delivered if the AF episode has lasted longer than about 48 hours. Moreover, a cardiac rhythm management device in which the patient has the ability to control whether an atrial shock is delivered, therefore, should also warn the patient if there has been a prolonged AF episode, which would make it risky to deliver a shock to treat the AF.
