Methods, systems and devices for optimizing cardiac pacing parameters

A device for improving cardiac performance associated with a current set of N pacing parameters by adjusting the N cardiac pacing parameters, where N is an integer greater than one, the device comprising:

• a sensing circuit that determines cardiac performance associated the current set of N pacing parameters and cardiac performance associated with sets of test pacing parameters;
• and
• a processor that for i=one to N
• increments an ith pacing parameter in the current set of N pacing parameters based on a corresponding ith increment value to thereby produce an ith set of test pacing parameters,
• updates the ith increment value based on the cardiac performance associated with the ith set of test pacing parameters as determined by the sensing circuit, and
• updates the current set of N pacing parameters based on the updated ith increment value.

A device for improving cardiac performance associated with a current set of N pacing parameters by adjusting the N cardiac pacing parameters, where N is an integer, the device comprising:

• a sensing circuit that determines cardiac performance associated the current set of N pacing parameters and cardiac performance associated with random sets of test pacing parameters;
• a random value generator that generates random test sets of N pacing parameters;
• and
• a processor that replaces the current set of N pacing parameters with a random test set of N pacing parameters if the cardiac performance associated with the random test set of N pacing parameters is greater than the cardiac performance associated with the current set of N pacing parameters.
