Detecting Atrial Fibrillation After Stroke Using Different ECG Devices and Timing of Screening

What this Trial Is About

Researchers are investigating atrial fibrillation AF, a common heart rhythm problem linked to 20-30% of all strokes. Detecting AF early after a stroke is important because AF-related strokes tend to be more severe, but the best timing and devices for screening are not yet well defined. This study aims to find out if screening for AF right after stroke symptoms begin detects more cases than screening after hospital discharge and whether a 3-lead ECG device improves detection compared to a 1-lead patch recorder. The study involves patients admitted with acute stroke who do not have AF at admission or have paroxysmal AF but show normal heart rhythm when admitted. Participants will receive 48 hours of continuous heart monitoring in the hospital, followed by another 48 hours after discharge. A subgroup will also perform intermittent handheld ECG recordings three times daily for 30 seconds over three days during their hospital stay. The study compares continuous versus intermittent monitoring and different device types to see which detects AF more effectively. During their participation, patients will undergo heart rhythm monitoring with ECG devices and complete handheld ECG tests if selected. Researchers will track AF detection rates during 48 to 96 hours post-stroke, comparing results based on timing and device type. The study evaluates outcomes like the rate of AF detection with different monitoring strategies, aiming to improve early diagnosis to help prevent recurrent strokes. Participation includes monitoring during hospital stay and after discharge, with follow-up lasting up to about four days of recording.
