First generation LUX-Dx™ ICM System demonstrated highest overall PPV5
An independent abstract presented at HRS 2024 evaluated real-world arrhythmia detection accuracy across all ICM manufacturers. A total of 652 patients with 18,665 alerts were randomly selected across multiple centers and analyzed for rates of true and false positive transmissions. They found the first-generation LUX-Dx ICM System had the highest overall Positive Predictive Value (PPV) across all ICMs evaluated.

LUX-Dx II+ ICM System Dual-Stage Algorithms
Enhanced atrial fibrillation algorithm
The AF algorithm uses R-R variability to detect potential AF rhythms. The verification stage uses several criteria including adaptive morphology, noise discrimination and pattern detectors to identify and reject false positives. New with the LUX-Dx II+ ICM is an additional verification step to identify sequential heart rate patterns and an update to merge adjacent AF episodes.
Enhanced atrial fibrillation algorithm
Novel PVC burden algorithm with programmable alert
This algorithm uses a patient-specific morphology assessment to detect potential premature ventricular contraction (PVC) sequence types like couplets and triplets. It provides a daily burden percentage with advanced programming and is the only ICM with an actionable PVC Burden alert.*
Novel PVC algorithm
Enhanced pause algorithm
This algorithm continues to use R-R intervals to detect pause episodes. The enhanced verification step further rejects false positives due to a low Signal-to-Noise Ratio. Additionally, the LUX-Dx II+ ICM is the only ICM with advanced nighttime pause programming*—to detect, differentiate and record specified nighttime pause events separately.
Enhanced pause algorithm
Enhanced bradycardia algorithm
The algorithm continues to use rate and duration parameters during the detection stage to identify potential brady episodes. During the verification stage, episodes are further examined and rejected if undersensing is identified. New with the LUX-Dx II+ ICM is advanced nighttime programming to detect, differentiate and record specified nighttime Brady events separately.
Enhanced brady algorithm
Atrial tachycardia algorithm
The AT algorithm uses rate, duration and built-in flexibility to detect either short or long duration AT or Atrial Flutter based on heart rate and R-R variability. The LUX-Dx II+ ICM System is the only ICM with independent AT and AF programming,* enabling better detection of clinically relevant regular arrhythmias—without compromising ideal AF detection settings.
Atrial Tachycardia algorithm
Tachycardia algorithm
This algorithm uses traditional ICD-based rate and duration parameters during the detection stage. The verification stage uses a machine-learning-based decision tree to classify Tachy episodes as VT, SVT or to reject as noise.
