Implication
The Reveal LINQ ICM atrial fibrillation detection algorithm demonstrates high positive predictive value for episodes ≥1 hour, though performance varies significantly based on the underlying patient indication and episode duration.
Structured PICO
P
Population
3,759 consecutive patients with implanted insertable cardiac monitors (ICMs) for indications of syncope (n=1604, 43%), known atrial fibrillation (n=1049, 28%), or cryptogenic stroke (n=1106, 29%).

Intervention
Reveal LINQ insertable cardiac monitor (ICM) with enhanced atrial fibrillation detection algorithm
O
Outcome
Episode detection positive predictive value (PPV) and true/false detection rates for atrial fibrillation episodes of different durationssurrogate
The Reveal LINQ ICM atrial fibrillation detection algorithm demonstrates high positive predictive value for episodes ≥1 hour, though performance varies significantly based on the underlying patient indication and episode duration.
