Noise Reducing Technology
Acquire raw intracardiac signal information without distortion and view cardiac signals in their pure, original format.
Cardiac Signal Insights with Unprecedented Clarity and Precision
PURE EP™ reveals unprecedented levels of signal clarity, providing advanced visualization of critical physiologic information for intracardiac signals — even the most complex.
PURE EP™’s Algorithmic Noth (AN) can eliminate environmental noise without harmonic ringing. Conventional classic notch (CN) creates artifact and signal attenuation, introducing false and misleading physiologic fractionation.
Full-Spectrum Intracardiac Signal Insights with Proprietary Technology
Signal Data Preservation
Dynamic analysis allows for full-spectrum signal evaluation while highlighting and retaining a new level of signal specificity.
Wide Signal Capture
Detect the smallest signals without the need to gain switch, for clearer and more accurate visualization of both small and large signals.
Trusted Unipolar Data
Finally gain access to reliable unipolar data, with a cutting-edge signal pathway that emulates bipolar data acquisition.
Enhanced Visualization
A large frequency bandwidth preserves intracardiac signals within the cardiac window.
Clearly View the Cardiac Window of Interest
PURE EP™ reveals a never-before-seen view of the cardiac window of interest1 — the PURE ZONE™ — including critical signals at high frequency and low amplitude.

Proprietary Software-Based Features
Delivering configurable features, unique algorithms and signal hygiene applications, PURE EP™ offers the freedom to explore relevant signal data for highly tailored, efficient procedures.
High Frequency algorithm (HFA)
By focusing on signals above 200Hz, the High Frequency Algorithm (HFA) adds visibility to cardiac frequency data and dynamically eliminates RF frequencies to retain clear focus on the signals targeted for ablation.
HFA demonstrated 100% specificity of near field potentials with peak-to-peak voltages of <0.1mV.5

Automatic Tachycardia Characterization (ATC)
Subtle changes in complex tachycardias can be difficult to detect with the naked eye. Automatic Tachycardia Characterization (ATC) swiftly monitors tachycardia rates and conduction patterns in real-time, alerting changes that may warrant further evaluation.

Near Field Tracking (NFT)
Near Field Tracking (NFT) lets you track the reduction in the negative component of a unipolar intracardiac signal during ablation. Presenting a visual indication, NFT offers an automated queue when the loss of the negative component has been identified after three consecutive beats.
