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。

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。
