Cryptogenic cardioembolic stroke. (A) A patient develops atrial fibrillation, but the atrial fibrillation is not recognized by patient or physician. The patient, not receiving warfarin for stroke prophylaxis, suffers a cardioembolic stroke as a result of the atrial fibrillation. (B) The patient spontaneously converts from atrial fibrillation to sinus rhythm between the time of stroke onset and the time of presenting for medical attention. The patient with cryptogenic cardioembolic stroke is discharged without anticoagulation because the episode of atrial fibrillation remains unrecognized. (C) The patient experiences recurrent atrial fibrillation and is at high risk for new ischemic stroke both because of prior stroke and because the patient is not receiving anticoagulants.
