For SOP Instances of ECG acquired in the cardiac catheterization lab, the Defined TID for Acquisition Context Sequence (0040,0555) is TID 3403 “Catheterization Acquisition Context”. For routine resting or stress ECG, the Defined TID for Acquisition Context Sequence (0040,0555) is TID 3401 “ECG Acquisition Context”.

The value of Number of Waveform Channels (003A,0005) in each Waveform Sequence Item shall be between 1 and 13, inclusive. The total number of channels encoded across all Items shall not exceed 13.
This specialization provides for up to five Waveform Sequence Items (multiplex groups), with a total of 13 channels. This allows, for instance, encoding of four sets of three simultaneously recorded channels, the sets being acquired sequentially, plus one continuous channel for the duration of the other sets. This can be used to emulate the behavior of classical 12-lead ECG strip chart recorders with 4x3 presentation, plus a continuous lead II recording (see Figure A.34.3-1).
The value of Number of Waveform Samples (003A,0010) in each Waveform Sequence Item shall be less than or equal to 16384.
This allows over 16 seconds per channel at the maximum sampling frequency; if longer recordings are required, the General ECG IOD may be used.
The value of Sampling Frequency (003A,001A) in each Waveform Sequence Item shall be between 200 and 1000, inclusive.

The Defined CID for the Concept Name Code Sequence (0040,A043) in the Waveform Annotation Sequence (0040,B020) shall be CID 3335 “ECG Annotations”. This Context Group supports the annotation of suppressed pacemaker spikes in the ECG waveform.
