在心电图仪胸导联的联结中右上肢、左上肢及左下肢的三个电极各联接一个等值(5~500KΩ)的高电阻后相接于一点,此点的电位近似为零,称为“中心电端”(图1)。各
In the electrocardiograph chest lead connection in the right upper limb, left upper limb and left lower limb of the three electrodes each connected to an equivalent (5 ~ 500KΩ) of high resistance after a phase, the potential of this point is approximately zero, called “Center Electric” (Figure 1). each
