Finding Atrial Fibrillation in Patients With Unexplained Stroke Using Longterm Cardiac Monitoring
Stroke Prior to Diagnosis of Atrial Fibrillation Using Longterm Observation With Implantable Cardiac Monitoring Apparatus Reveal(SURPRISE) -the SURPRISE Study
The SURPRISE study investigates atrial fibrillation(AFIB) in patients with a previous unexplained stroke. It uses long term monitoring of the heart of up to three years, searching for paroxysmal atrial fibrillation(PAF) otherwise undetected in this population.

The SURPRISE study investigates the patients with cryptogenic stroke or transient ischemic attack (TIA), monitoring them with a cardiac loop recorder for up to three years.

it aims at estimating the amount of paroxysmal atrial fibrillation within our population of cryptogenic stroke patients.

Standard workup for a stroke patient does offer cardiac evaluation, but monitoring is limited to the time admitted, often just a few days.
