Patent ID: 8369947

Claim:
A nerve stimulation device comprising: a plurality of sets of electrodes disposed in different positions on a vagus nerve; a pulse outputting unit connected to each of the plurality of sets of electrodes, for outputting a pulse for stimulating the vagus nerve; a switching unit for switching the electrode to which the pulse from the pulse outputting unit is transmitted and; a cardiac beat detecting unit for detecting a cardiac beat of a heart, wherein the switching unit selects at least one set of electrodes from the plurality of sets of electrodes on the basis of the cardiac beat and a level of a cardiac rate detected by the cardiac beat detecting unit and transmits the pulse from the pulse outputting unit to the selected at least one set of electrodes; and wherein the switching unit stores in a data table of the cardiac rate reducing effects obtained by stimulating the vagus nerve using the electrodes individually at the time of installation of each electrode, and determines at least one set of electrodes, to which the electric pulse is transmitted, from the plurality of sets of electrodes on the basis of the data table and a measurement result of cardiac rate by the cardiac beat detecting unit.
