Mapping System

Quantity of Data

The RHYTHMIA HDx Mapping System collects 25x more data points on average per map compared to conventional mapping systems.1

High point density reduces the amount of interpolation between annotated points, which allows you to more accurately visualize propagation patterns and more precisely identify small gaps and areas of interest.

  • ORION Catheter – 64-electrode design, which allows for the quick collection of large amounts of data.
  • Data Processing – There is no limit to the number of points on a map or case.


"The high numbers of electrodes provide comprehensive and accurate electrical information to enable insight into underlying AT mechanisms and activation patterns that have rarely been available in this detail before." 1

Quality of Data

The RHYTHMIA HDx Mapping System delivers the highest resolution of any system on the market through its low noise floor and unique mapping catheter design

High resolution mapping allows you to more clearly identify gaps in lesion sets, locate channels within dense scar, define scar boundaries and visualize propagation in even heavily diseased or scarred chambers.


“In severely scarred atria, this system is for the first time able to display low-voltage critical isthmuses (CI), which are far below the current scar cutoff of classically available systems.” 2

Visual Propagation

Speed and Accuracy of Data

The RHYTHMIA Mapping System enables continuous, rapid, automatic mapping with a novel annotation algorithm shown to deliver 99.98% accuracy, according to published clinical data.3

The procedure experience is further strengthened by the RHYTHMIA System's tracking accuracy ≤ 1mm with the INTELLAMAP™ and INTELLANAV™ portfolio of catheters.4


“The combination of increased sampling density, mapping resolution, and a novel algorithm to improve the accuracy of activation timing resulted in the ability to construct activation maps with better characterization of the circuit as compared to standard mapping technologies.” 5
