The standard 12-lead electrocardiogram (ECG) is only one of the possible ways to present the voltage differences between the nine recording electrodes. Other "non-conventional" leads may be constructed by physically connecting two or more electrodes in a different manner or by computation from the digital 12-lead ECG. Examples include bipolar or multipolar precordial leads and bipolar chest leads (between one precordial and one limb electrode). Such leads can remove or decrease noise originating from a limb cable/electrode that is present in the unipolar precordial leads. They can be diagnostically useful in Brugada syndrome and can display QRS fractionation that is not visible in the respective unipolar precordial or limb leads. Multipolar precordial leads sometimes display potentially useful information that is not visible in the respective unipolar leads and in bipolar leads computed from them. In conclusion, these computed ECG leads represent a potentially useful supplement to the conventional 12-lead ECG.
标准12导联心电图（ECG）只是呈现九个记录电极之间电压差的一种可能方式。其他“非常规”导联可以通过以不同方式物理连接两个或更多电极或从数字12导联心电图进行计算来构建。示例包括双极或多极胸前导联以及双极胸导联（在一个胸前电极和一个肢体电极之间）。此类导联可以消除或减少源自单极胸前导联中存在的肢体电缆/电极的噪声。它们在 Brugada 综合征的诊断中可能有用，并且可以显示在相应的单极胸前或肢体导联中不可见的QRS波碎裂。多极胸前导联有时会显示在相应的单极导联以及由它们计算得出的双极导联中不可见的潜在有用信息。总之，这些计算得出的心电图导联是对传统12导联心电图的一种潜在有用的补充。
