PROBLEM TO BE SOLVED: To provide a movement detecting method for a nerve stimulation electrode, which can detect a movement of a nerve stimulation electrode detained in a blood vessel, properly along a blood vessel.SOLUTION: In a movement detection method for a nerve stimulation electrode, a nerve stimulation electrode 10 is positioned in a blood vessel Sv, and a measured value of a biological signal detected at a reference time is stored as a reference biological signal measured value. While the nerve stimulation electrode 10 being detained in a blood vessel, the measured value of the biological signal to be detected and the stored biological signal measured value are compared thereby to decode whether or not the nerve stimulation electrode 10 has moved along the blood vessel Sv.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】血管内に留置される神経刺激電極の血管に沿った移動を好適に検知することができる神経刺激電極の移動検知方法を提供する。【解決手段】神経刺激電極の移動検知方法は、神経刺激電極10を血管Sv内で位置決めし、基準時刻に検出した生体信号の測定値を基準生体信号測定値として記憶し、神経刺激電極10を血管内に留置しつつ、検出する生体信号の測定値と記憶した基準生体信号測定値とを比較して、神経刺激電極10が血管Svに沿って移動したか否かを判定する。【選択図】図2
