Overview
Accuracy matters
The LINQ II™ ICM is the most advanced ICM system, featuring enhanced artificial intelligence (AI) algorithms, remote programming, and 4.5-year† longevity.1
LINQ II™ ICM is ideal for patients experiencing infrequent symptoms that require long-term monitoring or ongoing management. AccuRhythm™ AI algorithms are a groundbreaking platform that applies deep learning artificial intelligence algorithms to LINQ II™ data flowing into the CareLink™ network.
LINQ II™ ICM is the first insertable cardiac monitor with an indication for pediatric use.

Clinically meaningful and actionable alerts
Atrial fibrillation (AF) and Pause AccuRhythm™ AI algorithms further enhance the accuracy of the LINQ II™ ICM data.2–4 The cloud-based artificial intelligence system reduces false alerts while retaining true alerts, so you can maintain diagnostic yield and spend more time on the human side of care.
AccuRhythm™ AI algorithms are a groundbreaking platform that can seamlessly and remotely apply deep learning algorithms to already-transmitting LINQ II™ devices. They were rigorously trained and were developed based on over one million professionally adjudicated ECGs for smarter, more accurate insight without data bias.2
Improving accuracy while maintaining sensitivity
AccuRhythm™ AI algorithms further address the two most common sources of these ICM false alerts — AF and Pause.2,3,5
Validation data from real-world LINQ II™ ICM patients demonstrated:
- 97.4% reduction in false Pause alerts.
- 88.2% reduction in false AF alerts.
Preserved true alerts2:
- 99% true AF alerts preserved
- 100% true Pause alerts preserved
91% reduction in LINQ II™ ICM false alerts2
Check out how this impacts your clinic’s time. The AccuRhythm™ AI algorithms can save clinicians approximately 401 hours of false alert review yearly for every 200 LINQ II™ ICM patients.‡,§,2
‡ The validation study performance and time study results were projected onto 16,301 LINQ II™ patients to calculate the time saved per year in 200 LINQ II™ ICM patients.
§ Estimated time savings was calculated based on 11.3 minutes per non-actionable ICM transmission.6

MRI conditions for use
LINQ II™ insertable cardiac monitor (ICM) system
Conditionally safe MRI access SureScan™ technology
LINQ II™ ICM is MR Conditional at ≤ 3 T with no post-insertion waiting required.
A patient with a LINQ II™ device can be safely scanned in an MR system that meets the following conditions with no post-insertion waiting required. Failure to follow these conditions for use may result in a hazard to the patient during an MRI scan:
- Open or closed clinical MRI systems with a static magnetic field of ≤ 3 T must be used.
- Hydrogen proton MRI equipment must be used.
- Maximum spatial gradient of the static magnetic field specification must be ≤ 25 T/m (2500 gauss/cm).
- Whole body gradient systems with gradient slew rate specification must be ≤ 200 T/m/s per axis.
- The Whole Body Specific Absorption Rate (WB-SAR) as reported by the MRI equipment must be ≤ 4.0 W/kg; the head SAR as reported by the MRI equipment must be ≤ 3.2 W/kg.
- Do not use local transmit coils on the chest, trunk, or shoulder region.
- There are no restrictions on the placement of receive-only coils, and there are no restrictions on the use of local transmit or receive coils for imaging of the head or extremities.

Remote programming
First ICM with remote programming◊,1
LINQ II™ ICM enables remote programming capability for all device parameters post-insertion from the clinic, which may reduce patient office visits and scheduling hassles.
Patient data transmitted to CareLink™ network via MyCareLink Relay™ or MyCareLink Heart™
Clinician-initiated reprogramming via CareLink™ network
Monitors act as a
pass-through
Device settings automatically update without need for an office visit
