Leads avR, avL, avF, V11, V22, V33, V44, V55, and V66 are all unipolar leads. Since avR, avL, and avF are far away from the heart, the recorded potential difference is too small when the central electrode is the negative pole, so the negative pole is the average value of the potential sum of the other two limb leads except the probe electrode. Since this recording increases the potentials in the avR, avL, and avF leads, these leads are also referred to as stressed unipolar limb leads.

FIG. 7 is a functional block diagram of a first application embodiment of a mobile terminal with an electrocardiogram detection function provided by the present invention. Here, the mobile terminal is taken as an example for description. As shown in Figure 7, this is a schematic diagram of the acquisition work of the mobile phone with the electrocardiogram detection function provided by the present invention. The positive pole and negative pole of the group of leads are sent to the active electrodes of the analog front end after collecting physiological electrical signals on the human body. The amplifier is amplified, and the amplified signal is connected to the ECG signal lead interface of the mobile phone through the lead line. After the signal enters the mobile phone, after amplification, filtering and analog-to-digital conversion, the analog ECG signal becomes a digital signal.

由于在心电、脑电等生理信号的实际测量中，通常会使用皮肤清洁剂和导电胶来减小皮肤阻抗，增强皮肤和电极间的导电性，然而这种传统的测量方法需要很长的准备时间，而且会损坏人体的皮肤，不利于长期的测量，另一方面，生理信号测量时导连线会引入额外的噪声，对信号形成干扰，当生理采集信号微弱时这种干扰尤为严重。为了解决上述问题，本专利提出了一种有源主动电极设计方案，即直接在传统电极中集成模拟放大器，实现了生理测量信号放大及噪声减小的功能。In the actual measurement of physiological signals such as ECG and EEG, skin cleansers and conductive glue are usually used to reduce skin impedance and enhance the conductivity between the skin and electrodes. However, this traditional measurement method requires a long preparation time, and will damage the skin of the human body, which is not conducive to long-term measurement. On the other hand, the lead wire will introduce additional noise during physiological signal measurement, which will interfere with the signal. This interference is especially serious when the physiological signal is weak. In order to solve the above problems, this patent proposes an active electrode design scheme, that is, an analog amplifier is directly integrated in the traditional electrode, which realizes the functions of physiological measurement signal amplification and noise reduction.
