PURPOSE: A blood pressure variation measuring device is provided to measure the normal electrocardiogram and pulse of a patient by using a belt-type sensor and a band-type sensor. CONSTITUTION: An electrocardiogram sensor(110) is arranged in a breast belt(100). The electrocardiogram sensor has a surface electrode(111) and an active electrode(112). The active electrode senses an electric potential difference detected by the surface electrode. An armband has a plurality of first light emitting devices and a first light receiving part. The first light emitting device irradiates an infrared ray to an artery. The first light receiving part receives the infrared ray that is irradiated from the first light emitting device. A controller determines whether the signal that is detected by the armband is in a normal state. A 3D acceleration sensor(120) is arranged in the breast belt in order to sense the movement of a patient.
