Frausing et al. (2026) conducted a review in Cardiac implantable electronic device (CIED) therapy (n=133,000). Cardiac implantable electronic device (CIED) registry participation was evaluated on Positive predictive value (PPV) and completeness of procedural data variables. The Danish Pacemaker and ICD Register demonstrates high data completeness and excellent validity, with 23 of 29 procedural variables exhibiting a positive predictive value of at least 95%.
