Just like the precordial electrodes, aVR, aVL, and aVF - each detect any positive deflection coming towards them.

就像的电极aVR、aVL和aVF，这几个电极查指向它们的正电波。

All right as a quick recap - In a standard ECG there are 10 electrodes - four limb electrodes and six precordial electrodes that wrap around the chest.

得！快速回顾一下：标准的电图检查需要10个电极，位于肢体的4个电极和位于胸部的6个电极。

It’s also important to get an electrocardiogram, which typically shows tall, peaked T waves with a narrow base best seen in the precordial leads V1 through V6, as well as a shortened QT interval, and ST-segment depression.

做电图检查也十重要，一般情况下显示高、尖、窄基底T波，在V1到V6导联最容易见到，同时QT间隙长度变短，ST段压低。

In a standard ECG there are 10 electrodes - four limb electrodes, one on the left arm, right arm, left leg, and the right leg, and six precordial electrodes - V1 through V6 that wrap around the chest.

标准的电图检查需要10个电极，4个位于肢体的电极，位于左臂、右臂、左腿、右腿，6个位于的电极，从V1到V6，排列在胸部。
