本标准的目的是通过在主干电缆和患者导线连接器之间建立公共接口，允许ECG主干电缆和患者导线在具有隔离患者连接的ECG设备之间互换。还规定了用于隔离患者连接器的主干电缆和患者引线的性能和安全标准。本标准的原始范围与心脏监护仪使用的主干电缆和患者导线有关。该范围扩大到包括与其他ECG设备（包括诊断心电图机、动态ECG（Holter）记录仪/事件记录仪和ECG遥测）一起使用的患者导线。

The objective of this standard is to allow ECG TRUNK CABLES and PATIENT LEADWIRES to be interchanged between ECG DEVICES with isolated PATIENT connections by establishing a common interface between the TRUNK CABLE and the PATIENT LEADWIRE connectors. Performance and safety criteria for TRUNK CABLES and PATIENT LEADWIRES used with isolated PATIENT connectors are also specified. This standard's original scope related to TRUNK CABLES and PATIENT LEADWIRES used with cardiac monitors. The scope was extended to include PATIENT LEADWIRES used with other ECG DEVICES including diagnostic electrocardiographs, ambulatory ECG (Holter) recorders/event recorders and ECG telemetry.
