EGM Adjudication
Each transmitted EGM was manually adjudicated as either a true positive (TP) or a false positive (FP) episode. For each arrhythmia type, a TP day was defined as any patient-day that included at least one TP EGM.
Bradycardia and pause EGMs were adjudicated by a single reviewer, as their relatively objective classification resulted in negligible inter-observer discrepancies. As AF and tachycardia rhythms were more complex and often required further scrutiny, those EGMs were adjudicated by two independent reviewers. If agreement was not reached, a third reviewer was consulted. All EGM reviewers were blinded to patient demographics and clinical events.
