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.
