PROBLEM TO BE SOLVED: To stimulate vagus nerves efficiently while preventing the useless consumption of an energy.SOLUTION: The nerve stimulation device 1 comprises: a stimulus signal output unit 3 which outputs a stimulus signal to a vagus nerve B a cardiac event detection unit 2 which detects a cardiac event and a control unit 4 which determines the responsiveness of the heart A on the basis of the cardiac event that has been detected by the cardiac event detection unit 2 upon the output of the stimulus signal from the stimulus signal output unit 3 and controls the stimulus signal output unit 3 so as to decrease the intensity of the stimulus signal when the responsiveness of the heart A is decreased.COPYRIGHT: (C)2012,JPO&INPIT【課題】エネルギが無駄に消費されてしまうことを防止しつつ効率的に迷走神経を刺激する。【解決手段】迷走神経Bに刺激信号を出力する刺激信号出力部3と、心臓事象を検出する心臓事象検出部2と、刺激信号出力部3からの刺激信号の出力に対して心臓事象検出部2により検出された心臓事象から心臓Aの応答性を判定し、心臓Aの応答性が低下したときに刺激信号の強度を低下させるように刺激信号出力部3を制御する制御部4とを備える神経刺激装置1を提供する。【選択図】図1
