1. An implantable cardiac stimulation device for applying pacing stimulation pulses to a ventricle of a patient, the device comprising:

  • a pulse generator that is operative to generate the pacing stimulation pulses for delivery to the ventricle;

    a posture detector that is operative to sense posture of the patient; and

    control circuitry that is connected to the pulse generator and to the posture detector and that controls generation of the pacing stimulation pulses, wherein the control circuitry is operative to select an atrio-ventricular delay based solely on the sensed posture of the patient, wherein the control circuitry is operative to decrease the atrio-ventricular delay when the patient goes from a lying down position to an upright position, and to increase the atrio-ventricular delay when the patient goes from an upright position to a lying down position.
