Electrophysiology / RHYTHMIA™ Cardiac Mapping System / RHYTHMIA HDx™ Mapping / RHYTHMIA HDx™ Cardiac Mapping System Hardware

Scalable Hardware. Unprecedented Clarity.

The RHYTHMIA HDx Mapping System offers a scalable hardware platform offering automated, rapid acquisition of true high-definition maps that provide unparalleled clarity for accuracy, precision and efficiency in even the most complex cardiac procedures.

RHYTHMIA HDx Mapping System Signal Station

Designed to support high-density, high-resolution cardiac mapping, the RHYTHMIA HDx signal station:

  • Collects, processes and filters higher-quality signals
  • Features a clinically proven 0.01 mV noise floor, which means you can more clearly identify gaps in lesion sets, identify channels within dense scar, define scar boundaries, and visualize propagation in even heavily diseased or scarred chambers
  • Features 200 intracardiac channels—the most of any commercially available cardiac mapping system
  • Allows unlimited point collection
  • Enables true high-definition mapping when used with the INTELLAMAP ORION™ High-Resolution Mapping Catheter
  • Pairs with the INTELLANAV™ Ablation Catheters to give you confidence in the location of the catheter during therapy


The RHYTHMIA HDx localization system offers an advanced, flexible open architecture for diagnostic catheters.

Localization System

RHYTHMIA HDx features advanced, flexible open architecture that gives you the freedom to choose.

  • Impedance tracking supports cardiac mapping with non-navigation enabled catheters with a navigational accuracy of ≤2 mm¹
  • For optimal accuracy and efficiency, magnetic tracking supports mapping with Boston Scientific navigation-enabled catheters with a navigational accuracy of ≤ 1 mm
  • When paired with the INTELLAMAP ORION™ High-Resolution Mapping Catheter, RHYTHMIA enables high-definition cardiac mapping
