Abstract
A method of treating patients suffering from refractory hypertension includes identifying a patient suffering from the disorder and applying a stimulating electrical signal to the patient's vagus nerve predetermined to modulate the electrical activity of the nerve and to alleviate the hypertension. The step of applying the stimulation may be performed manually by the patient, or automatically following detection of the hypertension by sensing the patient's blood pressure, or, preferably by continuous or periodic application without use of a sensor. The stimulating signal is a pulse waveform with programmable signal parameter values including pulse width, output current, frequency, on time and off time.
