About EnSite Precision Cardiac Mapping System

The EnSite Precision™ Cardiac Mapping System allows for a high level of automation, flexibility and precision to help you diagnose a wide range of arrhythmias.1,2*

The EnSite Precision Cardiac Mapping System is designed to:

  • Let you choose the diagnostic and ablation catheters that best meet the needs of your patients.
  • Enhance VT mapping with automated, advanced morphology matching capability when using the EnSite™ AutoMap module and TurboMap feature.1
  • Automatically reject catheter ectopy.
  • Feature new timing detection algorithms including Last Deflection.
  • Help you create faster high-density maps of any chamber.1,**
Product Details

EnSite Precision Cardiac Mapping System Product Information



The EnSite Precision™ Cardiac Mapping System is a suggested diagnostic tool in patients for whom electrophysiology studies have been indicated. The EnSite Precision™ System interfaces to either the MediGuide™ Technology System or the EnSite Precision™ Module to combine and display magnetic processed patient positioning and navigation mapping information. When used with the EnSite™ Array™ Catheter, the EnSite Precision™ Cardiac Mapping System is intended to be used in the right atrium of patients with complex arrhythmias that may be difficult to identify using conventional mapping systems alone. OR, when used with an EnSite Precision™ Surface Electrode Kit, the EnSite Precision™ Cardiac Mapping System is intended to display the position of conventional electrophysiology (EP) catheters in the heart.

EnSite Precision Cardiac Mapping System Clinical Evidence

Journal articles, abstracts and other clinical evidence have analyzed the tracking and navigation accuracy, point collection, techniques and speed of the EnSite Precision Cardiac Mapping System. For a deep dive into the clinical data, visit the Clinical Evidence and Journal Article information.

Highlights from Accuracy Testing and Verification²

Performance bench testing was conducted to verify the tracking and navigation accuracy of the magnetic navigation and visualization technology in the EnSite Precision Cardiac Mapping System. This study tested the tracking accuracy and the navigation accuracy of the EnSite™ NavX™ Sensor Enabled™ technology in the EnSite Precision module with the FlexAbility™ ablation catheter, Sensor Enabled™ and the Advisor™ FL circular mapping catheter, Sensor Enabled™.
