1. A medical device programmer, comprising:

  • a receiver/transmitter circuit for communicating with an implantable cardiac device;

    circuitry for receiving data from the implantable cardiac device that includes a timing relationship between intrinsic ventricular depolarizations of the left and the right ventricle; and

    ,circuitry for selecting between a right ventricular, left ventricular, or biventricular pacing mode by which to provide pacing pulses based on the timing relationship between intrinsic ventricular depolarizations of the left and the right ventricle, wherein the selected pacing mode determines the manner in which paces are delivered over multiple cardiac cycles.
