PROBLEM TO BE SOLVED: To provide a method for measuring an electrocardiogram with reduced noise, and clothes for measuring the electrocardiogram capable of measuring such the electrocardiogram.SOLUTION: A method is provided for measuring an electrocardiogram of a human body. The method is characterized by measuring the electrocardiogram as follows: a first sensor is brought into abutment with any position in an area surrounded by a central line of a breastbone of a human body front side, a left front axillary line, the fifth rib upper end, and the eighth rib lower end; a second sensor is brought into abutment with any position in the area surrounded by the central line of the breastbone of the human body front side, a right front axillary line, the fifth rib upper end, and the eighth rib lower end; and a third sensor is brought into abutment on a perpendicular when drawing the perpendicular relative to the line for connecting the first sensor center and the second sensor center from the center point of the line for connecting the first sensor center and the second sensor center toward the head direction of the human body.SELECTED DRAWING: Figure 2【課題】ノイズの低減された心電図が測定できる測定方法と、このような心電図を測定することのできる心電図測定用衣服の提供。【解決手段】人体の心電図を測定する方法であって、 人体前面の胸骨の中心線と、左前腋窩線と、第五肋骨上端および第八肋骨下端に囲まれた領域内のいずれかの位置に第1センサーを当接させ、 人体前面の胸骨の中心線と、右前腋窩線と、第五肋骨上端および第八肋骨下端に囲まれた領域内のいずれかの位置に第2センサーを当接させ、 第1センサー中心と第2センサー中心とを結ぶ線の中点から、第1センサー中心と第2センサー中心とを結ぶ線に対して垂線を人体の頭部方向へ引いたときの垂線上に第3センサーを当接させて心電図を測定することを特徴とする心電図測定方法。【選択図】図2
