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

像心前区的电aVR、aVLaVF，这几个电分别探查指向它们的正电波。

There, now we see she's doing a precordial thump.

在那里，现在我们看到她在做心前区重击。

The chest leads, or precordial leads, view the heart in a HORIZONTAL plane.

胸导联或心前导联在水平面监测心脏。

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：标准的心电图检查需要10个电，于肢体的4个电于胸部心前区的6个电。

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.

做心电图检查也十分重要，一般情况下显示高、尖、窄基底T波，在心前区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.

标准的心电图检查需要10个电，4个于肢体的电，分别于左臂、右臂、左腿、右腿，6个于心前区的电，从V1到V6，排列在胸部。
