PROBLEM TO BE SOLVED: To provide an electrocardiographic device for vehicles capable of suitably reducing noise caused by a running vehicle.;SOLUTION: A electrocardiographic device for vehicles includes a direct electrode 11 mounted on a steering wheel 1, a first capacitively coupled electrode 13 and a second capacitively coupled electrode 15 mounted on a backrest part 3a of a seat 3, an electrocardiographic appliance 17, and so on. The first capacitively coupled electrode 13 is mounted so as to be located at an upper and left side of the second capacitively coupled electrode 15 when seen from a front side of the seat 3. The second capacitively coupled electrode 15 is located at a low and right side relative to the first capacitively coupled electrode 13. The electrocardiographic appliance 17 outputs a potential difference between a body potential detected by the direct electrode 11 and a body potential detected by the second capacitively coupled electrode 15, filters electrocardiographic signals based on the potential difference and takes samples at a predetermined period to acquire an electrocardiographic wave form.;COPYRIGHT: (C)2014,JPO&INPIT
