Atrial Fibrillation (AF) and Pause AccuRhythm AI algorithms further enhance the accuracy of the LINQ II ICM data.1-3 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.4

Why use AccuRhythm AI algorithms?

Leveraging more than 20 years of ICM expertise and a robust history of in-human ICM data, Medtronic is uniquely equipped to build deep learning AI algorithms that evaluate the entire waveform in ICM ECGs.4

Check out how this impacts your clinic's time. The AccuRhythm AI algorithms can save clinicians approximately 319 hours of false alert review yearly for every 200 LINQ II ICM patients.*5

 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.

Advancing care by pursuing perfect accuracy

The platform's algorithms can be applied to all LINQ II ICM devices already enrolled in the CareLink network, providing immediate benefits to clinicians managing LINQ II ICM patients. AccuRhythm AI algorithms start by building on the performance of the Medtronic ICMs that came before them and were designed to support future innovations to continue seamlessly improving clinician experience.
