Why BioTel Heart MCOT™ to detect AF * in cryptogenic stroke patients? At 21 days, the likelihood of detecting post-stroke AF was more than five times higher with mobile cardiac outpatient telemetry than with implantable loop recording.‡ 2

We’d know about it. AHA/ASA† Stroke Prevention Guidelines:

For patients who have had an acute ischemic stroke or TIA with no other apparent cause, prolonged AF monitoring (≈30 days) is reasonable within 6 months of the event.1
