The similarity between and the number of limb lead cables play an important role in the frequency of incorrect connection of limb electrodes. Hence, a modified electrocardiogram (ECG) acquisition procedure is proposed in this brief communication, whereby the left-leg (LL) and right-leg (RL) electrode cables are combined into 1 cable, referred to as combined LL/RL cable. The electrode wires in the combined LL/RL cable are connected to 2 electrodes placed on both sides of the LL. The combined LL/RL cable is unique enough (being thicker) not to be mistaken with the upper limb electrode cables. The proposed modification will not in any way influence the ECG waveforms or amplitudes, and it can be expected to substantially reduce incorrect limb electrode placements.
肢体导联电缆之间的相似性以及其数量在肢体电极错误连接的频率中起着重要作用。因此，在本简短通讯中提出了一种改进的心电图（ECG）采集程序，据此将左腿（LL）和右腿（RL）电极电缆合并为一根电缆，称为LL/RL合并电缆。LL/RL合并电缆中的电极线连接到放置在LL两侧的两个电极上。LL/RL合并电缆足够独特（更粗），不会与上肢电极电缆混淆。所提出的改进不会以任何方式影响心电图波形或幅度，并且有望大幅减少肢体电极放置错误的情况。
