Abstract
A method and system for setting the operating parameters of a cardiac rhythm management device in which a plurality of parameter optimization algorithms are available. A measured feature of an electrophysiological signal such as QRS width has been shown to be useful in selecting among certain parameter optimization algorithms.
Claims21
1-32. (Canceled)
A method for delivering cardiac resynchronization therapy, comprising:
- varying the values of one or more resynchronization pacing parameters while measuring an intrinsic atrial rate;
- extracting a feature from an electrogram signal;
- and,
- setting one or more resynchronization pacing parameters based one or both of the feature extracted from an electrogram signal and the value of a resynchronization pacing parameter which tends to reduce the intrinsic atrial rate.
1 more element
A system, comprising:
- an implantable pulse generator for delivering resynchronization pacing therapy;
- wherein the pulse generator is programmed to vary the values of one or more resynchronization pacing parameters while measuring an intrinsic atrial rate;
- a controller programmed to extract a feature from an electrogram signal;
- and,
- wherein the controller is further programmed to select one or more optimum values of resynchronization pacing parameters based one or both of the feature extracted from an electrogram signal and the value of a resynchronization pacing parameter which tends to reduce the intrinsic atrial rate.
