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 by 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 value search range of at least one additional CRT optimization process based on the first recommended value, the first CRT optimization process based on a different process of optimization with respect to the at least one additional CRT optimization process;

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

    determining the value of the CRT parameter for use in delivery of CRT by the cardiac device based on the additional recommended values returned by the one or more additional CRT optimization processes.
