心电信号是一种低频微弱的生物电信号。对体表电极测量而言，信号幅度在10μV到4mV之间，典型值为1mV。频率范围在0.05Hz到250Hz，频谱能量主要集中在0.25Hz～35Hz之间。由于心电信号检测的信号源是人体本身，而人体又处在各种纷繁复杂的电磁环境中，心电信号中不可避免地会混有各种高强度的干扰。常见的干扰有以下几种：
Heart electrical signal is a low frequency weak biological electrical signal. To Tibiao electrode measurements, the signal in the range of 10 V to 4mV 16ug between typical value for 1mV. In 0.05Hz to 250Hz frequency range, mainly in the energy spectrum 0.25Hz~35Hz between. Because heart electrical signal detection signal source is the body itself, and also in various human complex electromagnetic environment, heart electrical signal that inevitably mixed with a variety of high-intensity jamming. Common interference with the following :
