  Purpose

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.

Estimated Enrollment: 100
Study Start Date: April 2010
Estimated Study Completion Date: October 2013
Detailed Description:

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.
