Signal quality

This signal changes everything

Healthcare ProfessionalsElectrophysiology / LUX-Dx™ ICM / Signal Quality
With clear S-ECG signal quality from the moment of insertion, the LUX-Dx™ Insertable Cardiac Monitor (ICM) helps you achieve more efficient and confident event reviews. In fact, the signal quality is so clear, P-waves are visible in 90% of heart cycles and consistent over time.1


Astoundingly clear signals from the moment of insertion

The S-ECG signal quality of the LUX-Dx ICM is designed to emulate Lead II. It puts the power of clear signals in your hands from the very moment of insertion, giving confirmation of proper device location and confidence in algorithm performance.

Strong signal amplitude and exceedingly clear S-ECGs allow teams to work with actionable, high-quality data to increase confidence, minimize disruptions and streamline workflow.

LUX-DX Signal Quality Experience with Dr. Mark Richards
Dr. Mark Richards talks about how the ability to see clear signals and P-waves with the LUX-Dx ICM helps improve care and enhance workflow efficiency from the point of insertion through the day-to-day management of ICM patients.
