Abstract
The invention relates to an active implantable medical device. The device includes a VNS pulse generator, an activity sensor for detecting a patient's current activity level, and a processor. The processor is configured to collect the electrical activity of the heart, such as a current intrinsic heart rate of the patient. The processor further calculates values of a reference heart rate based on the patient's current activity level. A first histogram is constructed from the reference heart rate values, and a second histogram is constructed from the intrinsic heart rate values. An index representative of the patient's condition is derived by comparing the first and second histograms.
