Abstract
A cardiac pacemaker having a pacing rate responsive to a control function of a physiological parameter indicative of activity levels. The coefficients of the function are automatically calculated and modified in response to the trend of the measured physiological parameter in order to correspond to the patient real needs. For monitoring the physiological parameter minute ventilation (VE), the basic value VE low and maximum value VE max are calculated in order to vary the slope and intercept of the straight line representative of the control relation of the pacing rate FC by the minute volume VE.
