Silent Atrial Fibrillation Increases Stroke Risk

Atrial tachyarrhythmias in the absence of clinical atrial fibrillation (AF) occur frequently among patients with pacemakers and are associated with a significant increase in the risk for stroke or systemic embolism over time. Results of the Asymptomatic AF and Stroke Evaluation in Pacemaker Patients and the AF Reduction Atrial Pacing Trial (ASSERT) show that in this population of patients with pacemakers who have hypertension but no history of AF, episodes of device-detected atrial tachycardia greater than 6 minutes were seen in approximately one third of patients during almost 3 years of mean follow-up.
