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.
