1. A method for operating a cardiac device to algorithmically determine a value of a parameter for use in delivery of cardiac resynchronization therapy (CRT), the method comprising:

  • implementing a first cardiac resynchronization therapy (CRT) optimization process including analyzing a first set of physiological signals and returning a first recommended value for a CRT parameter based on the first set of physiological signals;

    adjusting a CRT parameter search range of at least one additional CRT optimization process based on the first recommended value;

    implementing the at least one additional CRT optimization process including analyzing a second set of physiological signals and using the adjusted search range to return an additional recommended value for the CRT parameter; and

    determining the value of the CRT parameter for use in delivery of CRT by the cardiac device based on the additional recommended value.
