    sensing the patient'"'"'s level of exercise and level of left ventricular afterload;

    determining an adaptive heart rate R0 as a function of the patients level of exercise;

    determining a rate adjustment RA as a function of the patient'"'"'s level of ventricular afterload;

    adjusting the adaptive rate, R0, by the rate adjustment, RA, to provide exercise responsive pacing at a treatment rate, RT, corresponding to a desired level of left ventricular afterload;

    and delivering cardiac pacing therapy to the patient at the treatment rate.
