METHOD OF OPTIMIZING CARDIAC RESYNCHRONIZATION THERAPY USING SENSOR SIGNALS OF SEPTAL WALL MOTION

Title:

METHOD OF OPTIMIZING CARDIAC RESYNCHRONIZATION THERAPY USING SENSOR SIGNALS OF SEPTAL WALL MOTION

Document Type and Number:

WIPO Patent Application WO2005011803

Kind Code:

A3

Abstract:

The present invention relates to monitoring septal wall motion of the atrial and/or ventricular chambers of a heart for optomizing cardiac pacing intervals based on signals derived from said wall motion. At least one lead of the medical device is equipped with a motion sensor adapted to couple to the septal tissue. The device receives and may post-process motion signals to determine acceleration, velocity or displacement. During pacing interval optimization the wall motion is measured for many pacing intervals and the pacing interval setting(s) that produce minimal wall motion are implemented for therapy delivery of a bi-ventricular pacing therapy to a patient that may have experienced beneficial reverse remodeling of the heart.
