Consider a 55-year-old with narrow complex tachycardia, 180 bpm. During the EP study, the real-time recording showed a VA interval of 70 ms—suggestive of typical AVNRT. However, the physician was uncertain due to odd retrograde atrial activation. Later, using EP Evaluator 12, the team reviewed the case with variable speed and filtering. They discovered a subtle eccentric atrial activation (CS 9,10 earlier than CS 1,2) that was missed live. This changed the diagnosis to septal accessory pathway mediated AVRT. The patient underwent successful ablation in a second procedure. Without EP Evaluator 12’s offline analysis, the diagnosis would have remained incorrect.
One of the most significant pain points in a modern EP lab is the "Tower of Babel" problem—different recording systems (Bard Labsystem, GE CardioLab, Siemens Sensis, etc.) speak different data formats. EP Evaluator 12 acts as a universal translator. It can import data from virtually any EP recording system onto a single, unified review platform. This allows a lab to compare a historical study recorded on an old system with a current study on a new system side-by-side. ep evaluator 12
While 3D mapping systems (CARTO, NavX, Rhythmia) dominate AF ablation, EP Evaluator 12 is invaluable for post-ablation validation. By analyzing stored EGMs from a circular mapping catheter before and after pulmonary vein isolation, the operator can confirm entrance and exit block without re-induction. Consider a 55-year-old with narrow complex tachycardia, 180
EP Evaluator 12 is a clinical decision support software designed for electrophysiologists and cardiac arrhythmia teams to manage and analyze catheter ablation procedures and electrophysiology studies. Later, using EP Evaluator 12, the team reviewed
Older versions of EP software treated 3D anatomical maps as separate entities. EP Evaluator 12 seamlessly syncs intracardiac electrograms (EGMs) with corresponding 3D mapping data from systems like Carto (Biosense Webster) or EnSite (Abbott). You can click on a specific point on a voltage map and instantly see the raw EGM signal at that exact location and timestamp. This feature is invaluable for identifying scar boundaries or verifying ablation lesion integrity.
Cardiac electrophysiology (EP) has undergone a remarkable transformation over the past two decades. What once relied on manual measurements and subjective interpretation of intracardiac electrograms is now a data-intensive science requiring precision, speed, and reproducibility. At the heart of this transformation lies specialized software designed to bridge the gap between raw electrical signals and clinical decisions. Among these tools, EP Evaluator 12 has emerged as a leading solution—widely regarded as the gold standard for offline analysis of EP studies.
Whether you are an electrophysiologist, a cardiac catheterization lab director, a clinical researcher, or a fellow in training, understanding the capabilities and workflow of EP Evaluator 12 is essential. This article provides a deep dive into its features, clinical applications, technical advantages, and why it remains a preferred choice in high-volume EP labs worldwide.
