| 1. A method for identifying preferred control parameters for use in controlling an implantable cardiac stimulation device
for implant within a patient, the method comprising the steps of:
controlling the implantable device to deliver therapy to the heart of the patient during a series of consecutive periods that
are substantially equal in duration to one another and less than about 12 seconds each in duration by alternating, from one
evaluation period to another, between different sets of selected test control parameters and a set of reference control parameters;
detecting values representative of transient cardiac performance corresponding to the different sets of control parameters
during the evaluation periods; and
estimating optimal control parameters for maximizing cardiac performance based on a difference between the values representative
of transient cardiac performance during each consecutive pair of evaluation periods.
