Healthcare ProfessionalsHeart Failure / LUX-Dx™ ICM / Reject False Positives


The ICM with a Dual-Stage Algorithm and Remote Programming

Excessive false positives can drain a lot of your valuable time. The LUX-Dx™ Insertable Cardiac Monitor (ICM) System was designed to reject false positives with a dual-stage algorithm and remote programming capabilities that help you continually adjust detection parameters.



Dual-Stage Algorithm

Actionable, High-Quality Data

The LUX-Dx ICM System features a dual-stage algorithm that detects and then verifies data before sending results, so it can reject false positives, provide actionable insights and accelerate critical decision making.

LUX-Dx ICM Algorithms

Advanced Algorithms Enhance Accuracy and Efficiency

AF Algorithm

Monitors R-R variability to detect potential AF rhythms. The verification stage uses adaptive morphology, noise discrimination and pattern detectors to identify and reject false positives.

AT Algorithm

Uses rate, duration and built-in flexibility to detect only high-rate rhythms sustained for a prolonged period of time, or to detect short duration AT/Atrial Flutter. The AT algorithm is independent of AF algorithm.

Pause Algorithm

Monitors R-R duration to detect pause episodes. The verification stage rejects false positives by using a dynamic noise-reduction filter, signal-to-noise ratio and loss-of-signal conditions.

Brady Algorithm

Uses rate and duration parameters during the detection stage to identify potential brady episodes. During the verification stage, episodes are further examined for under-sensing before being rejected.

Tachy Algorithm

Uses traditional ICD-based rate and duration parameters during the detection stage. The verification stage uses a machine-learning-based decision tree to identify potential tachy episodes. If they are not within the rate zone, they’re rejected as noise.
