Overview
Accuracy matters
As one of the world's smallest ICMs,1-3 the Reveal LINQ™ ICM works continuously to capture comprehensive and actionable data up to three years.† The device features AccuRhythm™ AI algorithms, which is a groundbreaking platform that applies deep learning artificial intelligence algorithms to Reveal LINQ™ data flowing into the CareLink™ network.
† Reference the Reveal LINQ™ ICM clinician manual for usage parameters.
Powerfully small and simple
- The Reveal LINQ™ ICM is one-third the size of a AAA battery (1.2 cc).
- It has a minimally invasive, simplified insertion procedure.
- The device is 1.5T and 3T MRI conditional.‡
‡ Reveal LINQ™ has demonstrated to pose no known hazards in a specified MRI environment with specified conditions of use. Please see the Reveal LINQ™ MRI technical manual for more details.
One-third the size of a AAA battery
Experience the difference of Reveal LINQ™ ICM now with AccuRhythm™ AI algorithms for AF and pause.
Reveal LINQ™ ICM,4 the most studied ICM in the market — trusted in over 1 million implants4 is now enhanced with proven AI, providing smarter, more actionable data — without compromise. Preserving over 99.9% true pause and 98.2% true AF alerts relative to Reveal LINQ™ ICM, AccuRhythm™ AI algorithms significantly improve the clinic experience.5

How are AccuRhythm™ AI algorithms applied?
Data workflow
The AccuRhythm™ AI platform applies deep learning AI algorithms to Reveal LINQ™ ICM data flowing into the CareLink™ network to remove false AF and Pause episodes and significantly reduce clinic review burden.5

Reduce false alerts while maintaining sensitivity
AF and Pause generate ~90% of false alerts in the ICM space.6
The AccuRhythm™ AI algorithms can save clinicians approximately 102 hours of false alert review yearly for every 100 Reveal LINQ™ ICM patients.§,◊,5
85% cumulative reduction in Reveal LINQ™ ICM false alerts.5
- 99.9% preserved true pause alerts5
- 98.2% preserved true AF alerts5
§ The validation study performance and time study results were projected onto 86,383 Reveal LINQ patients to calculate false alert reduction per year in 100 Reveal LINQ ICM patients.
◊ Estimated time savings was calculated based on 11.3 minutes per non-actionable ICM transmission.6

¶ The CRYSTAL-AF Study was a randomized, controlled study conducted on 441 patients to assess whether long-term monitoring with Reveal™ XT is more effective than conventional follow-up (control) for detecting atrial fibrillation in patients with cryptogenic stroke.
#Based on Kaplan-Meier estimates.
Δ In the CRYSTAL-AF study, the control group included 88 conventional ECGs, 20 24-hour Holters, and 1 event recorder.
∞ 2018 ESC Guidelines for Diagnosis and Management of Syncope defined conventional testing as undefined physician discretion for monitoring excluding ICM, External Loop Recorder, Tilt Test, EP Study, Recurrent 12-lead ECG, or 7-day Holter monitor.
†† The REVEAL AF Study was a prospective, single-arm, multicenter study to quantify the incidence of AF in patients at high risk for but without previously known AF using an ICM (Reveal LINQ™ or Reveal™ XT).
