1. A method for performing pacing interval optimization, comprising:

  • (a) producing a signal indicative of cardiac contractions of a patient'"'"'s heart, as the patient'"'"'s heart is paced using different sets of pacing interval parameters;

    (b) obtaining measures of pulse amplitude from the signal; and

    (c) performing pacing interval optimization based on the measures of pulse amplitude by selecting one of the sets of pacing parameters corresponding to a greatest measure of pulse amplitude as a preferred set.
