DISTRIBUTION OF FALSE ARRHYTHMIC ALERTS FROM IMPLANTABLE LOOP RECORDERS IN THE PHILIPS GENEVA HEALTH SOLUTIONS IMPLANTABLE DEVICE REMOTE MONITORING DATABASE

Abstract

BackgroundImplantable loop recorders (ILR) are the gold standard for extended diagnostic cardiac monitoring. Accurate detection of arrhythmias is paramount to data integrity. Unnecessary remote transmissions generated due to oversensing or undersensing of the cardiac electrogram (EGM) is a significant source of data deluge in ILR monitoring.ObjectiveIllustrate the distribution of transmissions archived with False detection of Atrial Fibrillation (AF), Pause, Bradycardia, and Tachycardia due to oversensing or undersensing on ILR transmissions.MethodsA retrospective analysis of ILR transmissions processed in 2021 was performed utilizing discrete data from the Philips Geneva Health Solutions database. Transmissions were either forwarded to a practitioner for review or archived, if adjudicated as non-clinically actionable. Discrete data statements categorizing false triggers due to oversensing or undersensing were queried to obtain total transmissions with false events. In addition, data was stratified by manufacturer.ResultsIn 2021, 485,755 ILR transmissions were processed by Geneva Remote Technicians; 36% were forwarded to practitioners, 64% were archived. Transmissions archived due to oversensing or undersensing of the EGM were identified in 20% (97,691) of all processed transmissions; a False AF event occurred in 54% (59,661), False Pause in 33% (35,755), False Tachycardia in 10% (10,561), and False Bradycardia in 3% (3,673).ConclusionFigure 2: Distribution of ILR transmissions in 2021 archived due to oversensing or undersensing by event type.View Large Image Figure ViewerDownload Hi-res image Download (PPT) BackgroundImplantable loop recorders (ILR) are the gold standard for extended diagnostic cardiac monitoring.
