To provide a system for transmitting blood pressure reduction electrical stimulation to the heart of a patient capable of determining a desirable AV delay.SOLUTION: The atrium is paced and the ventricle is paced with a given (arbitrary) delay to obtain a desired blood pressure change. Then, the atrium is sensed, the ventricle is paced, the blood pressure change is observed, and the resulting blood pressure change is compared with the paced-atrium-paced-ventricle desired blood pressure change. In the case where the blood pressure changes are not substantially equal, the timing of the sensed-atrium-paced-ventricle stimulation is adjusted on the basis of the comparison. The new modified resulting blood pressure change is observed, and the modified blood pressure change is compared with the paced-atrium-paced-ventricle desired blood pressure change. Adjustment and observation may be repeated until the timing of the sensed-atrium-paced-ventricle stimulation achieves the same blood pressure change as the desired blood pressure change of the paced-atrium-paced-ventricle stimulation.SELECTED DRAWING: Figure 9
