## CID 3687 Electrophysiology Waveform Durations

This Context Group consists of the per-lead terms under the hierarchy of Reference ID MDC_ECG_TIME_PD in the ISO/IEEE 11073-10102 nomenclature.

The base terms from that hierarchy are included in the table below for reference. The per-lead base terms are pre-coordinated with concept discriminators for specific leads, and the code values for those pre-coordinated terms are arithmetically derived from the code values of the base terms. For the complete current list of terms and discriminator values, see the ISO/IEEE Standard. All pre-coordinated terms (measurements plus discriminators) within the identified hierarchy are part of this Context Group.

### Note

1. A prior version of this context group used codes from the SCP-ECG coding system.
