Monitoring Data

Long-term Monitoring for Better Patient Outcomes

The Reveal LINQ ICM continuously monitors patients for up to 3 years. Learn more about long-term heart monitoring for suspected AF, syncope, and cryptogenic stroke.

Cryptogenic Stroke



of patients who had AF would have been missed if only monitored for 30 days ll4


of cryptogenic stroke AF diagnoses occur between years 2 and 34


more AF detected at 36 months with ICM vs. conventional follow-up¶4


of patients in whom AF was detected received oral anticoagulants at 12 months4


ICM recommended for syncopal episodes
> 30 days apart5


of syncope diagnoses occur between years 2 and 37


more likely to reach a syncope diagnosis with ICM vs. conventional care#8


of Reveal ICM guided diagnoses led to treatment10

Suspected AF (REVEAL AF Study)**


of patients with AF would have been missed if only monitored for 30 days6


of patients with ICM-detected AF would be missed if monitoring stopped at 2 years6


more likely to reach a diagnosis with ICM in 12 months vs. one-time, 30-day monitor9


of patients with ICM-detected AF had a change in clinical management6

Reference the Reveal LINQ ICM Clinician Manual for usage parameters.
§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.
llBased on Kaplan-Meier estimates.
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).

Disclaimer: A controlled, head-to-head study evaluating the comparative performance of these devices has not been done.

††Based on AF episodes ≥ 2 minutes and in known AF patients. % of false positives = (1 – episode PPV). AF episodes PPV may vary between gross and patient average.
‡‡Lux-Dx ICM, Confirm Rx with SharpSense technology, and BIOMONITOR III have no published clinical evidence showing AF episode PPV or AF sensitivity.

The Reveal LINQ Insertable Cardiac Monitor is an implantable patient-activated and automatically activated monitoring system that records subcutaneous ECG and is indicated in the following cases:

  • Patients with clinical syndromes or situations at increased risk of cardiac arrhythmias
  • Patients who experience transient symptoms such as dizziness, palpitation, syncope, and chest pain, which may suggest a cardiac arrhythmia

This device has not been specifically tested for pediatric use.
