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. In one embodiment, one or more resynchronization pacing parameters are set based on one or both of the feature extracted from an electrogram signal and the value of a resynchronization pacing parameter which tends to minimize the intrinsic atrial rate.

2. A system, comprising:
-
an implantable pulse generator for delivering pacing pulses to one or both ventricles, wherein the implantable pulse generator is programmed to deliver the pacing pulses in an atrial-triggered pacing mode and in accordance with specified pacing parameters;
a processor programmed to extract a feature from a cardiac electrical signal; and
,wherein the processor is further programmed to select one or more optimum settings of pacing parameters based on the one or more features extracted from an electrogram signal and the value of a pacing parameter that tends to minimize the intrinsic atrial rate. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)
