Sweet spoT for cArdiac Rhythm monitorinG After sTrokE

The goal of this clinical trial is to compare the use of long-term vs. shorter-term heart monitoring to detect atrial fibrillation after stroke.Patients will be implanted with a loop recorder and will have study follow-up at 3-, 6- an 12-months after implantation.The investigators will evaluate 24 patients, between the 3 centers, in the same way the investigators plan to evaluate a larger number of participants (>1000) in a future study. This will allow us to learn if such a study is possible, identify potential implementation challenges, and develop strategies to overcome those difficulties.
