Cryptogenic Stroke Study

Long-Term Cardiac Monitoring for Detection of Atrial Fibrillation After Cryptogenic Stroke

The purpose of this study is to determine whether the Sleuth Implantable Loop Recorder will enhance detection of latent atrial fibrillation in patients after cryptogenic stroke.

Inclusion Criteria:

• Recent stroke (within 30 days) as defined by who has a sudden onset of focal neurological deficits presumed vascular etiology and lasting more than 24 hours.
• Negative brain image for hemorrhagic stroke
• In sinus rhythm at time of enrollment

Exclusion Criteria:

• Know history of atrial fibrillation
• Previous implanted cardiac device (ppM or ICD)
• Serious illness making it unlikely to survive one year
• Known secondary cause of stroke
