HIGH DENSITY ATRIAL FIBRILLATION CYCLE LENGTH (AFCL) DETECTION AND MAPPING SYSTEM

摘要

Systems and methods to assist in locating the focus of an atrial fibrillation include the association of atrial fibrillation cycle length values and statistics relating thereto with temporal locations on an electrogram of a given electrode, and/or the coordination of electrode locations with respective the spectral analyses of electrogram signals and further parameters and statistics relating thereto. Ablation therapy can proceed under guidance of such information.

1. A system for mapping electrical activity of a heart, the system comprising:
a catheter shaft; a first electrode and a second electrode coupled to the catheter shaft; and a processor coupled to the catheter shaft, wherein the processor is designed to:
collect a first signal sensed by the first electrode and a second signal sensed by the second electrode over time;generate a first frequency representation corresponding to the first signal and a second frequency representation corresponding to the second signal;determine a first frequency parameter corresponding to the first frequency representation and a second frequency parameter corresponding to the second frequency representation; andcompare the first frequency parameter to the second frequency parameter.
