Abstract
An electronic pacemaker generating pacing signals includes both a metabolic rate responsive sensor monitoring a physiological parameter and an activity rate responsive sensor monitoring movement of a patient's body during exercise. The measurements from each of the sensors are used to develop a corresponding rate signal and the two signals are combined to generate a dual sensor rate used to determine the timing of the pacing signals. The physiological parameter may be for example minute volume variation while the body movement may be monitored for example by using an accelerometer. The activity rate responsive sensor output is preferably used as an indication of a transition of a level of exercise, when a faster change in the pacing rate is desirable.
