Abstract: A device and a method for analyzing an input signal (1) representing a neural activity of a nerve containing nerve fibers originating from baroreceptors from a patient. E.g. neural activity recorded with an electrode implanted to detect Vagus nerve activity. The invention is based on the insight that this neural activity can be used to determine a value indicative of the patient's blood pressure (BP). An ECG signal (2) can be used for deriving a trigger feature for processing of the nerve activity data, e.g. to arrive at a profile of the patient's Blood Pressure Pulse. E.g. the device can include a Vagus nerve stimulation unit which is controlled in response to an output from the calculation of blood pressure (BP), and/or features related to the Blood Pressure Pulse.

Abstract: The present invention relates to a medical device for analyzing cardiac related input signals. The device is capable of receiving an ECG-signal and a nerve activity signal, such as vagus nerve signal in order to detect a cardiac related neural activity, such as epilepsy. The device is programmed for detecting a trigger feature (e.g. the R-peak) in the signal and extracting a nerve activity signal segment from the nerve activity signal in response to detecting the trigger feature. An activity related feature is generated either based on a combined signal obtained from a number of nerve activity signal segments, or as a segment-based activity related feature obtained from a number of nerve activity signal segments. Moreover, the device is adapted for comparing the activity related feature to a predefine criterion in order to detect the cardiac related neural activity.
