1. A method, including:

  • sensing a first cardiac signal from a ventricular location;

    detecting ventricular depolarizations from the first cardiac signal;

    determining a heart rate based on the ventricular depolarizations;

    comparing the heart rate to a first predetermined value and a second predetermined value, the second value larger than the first value;

    setting a maximum ventricular pacing rate to the first predetermined value when the heart rate exceeds the second predetermined value; and

    setting the maximum ventricular pacing rate to the second predetermined value when the heart rate falls below a predetermined threshold.
