Patent ID: 6904317

Claim:
In an implantable cardiac stimulation device having a pulse generator for generating pacing pulses for applying to a heart of a patient and having a control circuit for controlling the pulse generator to apply overdrive pacing pulses to the heart using a set of control parameters, a method, performed by the control circuit, for automatically adjusting the control parameters comprising: acquiring an initial set of control parameters; controlling the pulse generator, based on the set of control parameters, to overdrive pace the heart; determining a degree of overdrive pacing achieved using the selected set of control parameters; adjusting the set of control parameters so as to improve the degree of overdrive pacing to be achieved during further overdrive pacing; acquiring a desired overdrive pacing range; and inputting an order of priority of control parameter adjustment and wherein adjusting the set of control parameters is performed sequentially to hierarchically adjust the control parameters in the input order of priority.
