LINE OF BLOCK DETECTION

摘要

Cardiac catheterization is performed by recording electrograms from a multi-electrode probe at respective locations in the heart, determining slopes and annotations in the electrograms within time windows, establishing relationships among the slopes and annotations of the electrograms, and determining lines of conduction block in the heart from the relationships.

主权项

1. A method, comprising the steps of:
inserting a probe into a heart of a living subject, the probe having a plurality of electrodes; recording electrograms from the electrodes at respective locations in the heart; determining slopes and annotations in the electrograms within time windows; establishing relationships among the slopes and annotations from different ones of the electrograms; and determining from the relationships lines of conduction block in the heart.
