Prevalence of Sub-Clinical Atrial Fibrillation in Elderly Patients With Hypertension, Detected Using an External Loop Recorder

Patients in the ASSERT III study will be monitored over a 60 day period for the development of subclinical AF via an external loop recorder. The device will automatically record and transmit ECGs through a BlackBerry Smartphone. The primary hypothesis is that among this elderly population with hypertension and a least one other risk factor for AF, the monitoring will detect AF in at least 10% of patients who would be potential candidates for anticoagulant therapy.
