Solution Overview

Problem

Current methods for generating electroanatomic maps of the heart often require manual separation of arrhythmia morphologies, which is time-consuming and inefficient, especially when dealing with multiple arrhythmias present in a patient's data.

Innovation Solution

The method automatically generates multiple electroanatomic maps by analyzing intracardiac electrograms morphologically and using pre-defined or adaptively created templates to classify beats based on their morphologic characteristics, allowing for real-time comparison and inclusion or rejection of beats in the maps.

AI summary

Cardiac electrograms are recorded in a plurality of channels. Beats are classified automatically into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates. Respective electroanatomic maps of the heart are generated from the classified beats.
