Lead I uses the Right Arm as the negative pole and Left Arm as the positive pole, forming a vector that goes to the right.

I导联将右作为负极，左作为正极，形成一指右侧（左）量。

And so there's two different poles, a negative and a positive pole here.

这里有不同极，一负极和一正极。

They use ONE limb electrode as the positive pole, and take the average of inputs from the OTHER two as the zero reference.

它们将1肢体电极作为正极，并取另肢体电极输入平均值作为零参考。

Thus, the position of the positive pole is the " point of view" , and the line connecting the 2 poles is the " line of sight" .

因此，正极位置是“视角”，连接极线是“视线”。

The corresponding chest electrodes serve as the positive poles.

相应胸电极是正极。
