An apparatus comprising: a first displacement current sensor comprising a first sensing electrode and a first guard electrode, wherein the first displacement current sensor is configured to measure afirst sensed signal dependent upon electrical activity of a subject's heart; a second displacement current sensor comprising a second sensing electrode and a second guard electrode, wherein the seconddisplacement current sensor is configured to measure a second sensed signal dependent upon electrical activity of a subject's heart; and circuitry configured to process at least the first sensed signal to compensate for artefacts arising from motion of the subject. 一种装置，包括：包括第一感测电极和第一保护电极的第一位移电流传感器，其中，第一位移电流传感器被配置为测量取决于对象的心脏的电活动的第一感测信号；包括第二感测电极和第二保护电极的第二位移电流传感器，其中，第二位移电流传感器被配置为测量取决于对象的心脏的电活动的第二感测信号；以及电路，被配置为至少处理第一感测信号以补偿由对象的运动引起的伪影。
