Twelve-lead electrocardiograms (ECGs) record 12 different views of cardiac electrical activity, or leads. They therefore provide more information than bedside monitors, which usually record one or sometimes two leads. Many acutely ill patients have 12-lead ECGs recorded either on admission to hospital, before undergoing operations or when specific cardiac concerns have arisen. Traditionally, ECGs have aided clinical diagnoses and, by learning how to understand and interpret them, nurses will know when they need to summon expert help. This article describes what each of the 12 leads represents, outlines the main indications for recording 12-lead ECGs and identifies likely causes of error in interpreting them.
十二导联心电图（ECG）记录心脏电活动的12个不同视角，即导联。因此，它们比床边监护仪能提供更多信息，床边监护仪通常记录一个导联，有时记录两个导联。许多急症患者在入院时、手术前或出现特定心脏问题时会进行十二导联心电图检查。传统上，心电图有助于临床诊断，通过学习如何理解和解读心电图，护士将知道何时需要寻求专家帮助。本文描述了12个导联各自代表的意义，概述了记录十二导联心电图的主要适应症，并指出解读心电图时可能出现的错误原因。
