RHYTHMIA HDx™ Mapping System

The RHYTHMIA HDx™ Mapping System offers industry-defining cardiac mapping, a powerful analysis toolset designed to streamline targeting and clinical decision-making, and unique insights into tissue substrate and lesion formation during RF ablation. Taken together, the elements of RHYTHMIA HDx provide unrivalled speed and precision in cardiac mapping and enhanced guidance in ablation delivery, helping physicians optimize treatment approaches and patient outcomes.

Designed to intelligently capture and automatically annotate high-fidelity EGM signals, RHYTHMIA HDx provides a more complete picture of cardiac electrical pathways. The system combines advanced signal-processing hardware, a cardiac mapping algorithm that can rapidly process unprecedented amounts of data, and the INTELLAMAP ORION™ High-Resolution Mapping Catheter. Its small, flat, printed electrodes capture signal only at the electrode-tissue interface, significantly reducing signal noise to a low 0.01mV. The result is an enhanced clarity and depth of detail in cardiac mapping and greater confidence in tailoring treatment.
A comprehensive portfolio of mapping and RF ablation solutions, RHYTHMIA HDx sets the standard for high-definition mapping, streamlines the identification of areas of clinical interest, and offers critical insights into tissue resistivity and lesion formation.
