FFF.2.1.1.4.1 Enhanced XA image without cardiac synchronization

In this example, the Enhanced XA image does not contain information of the cardiac cycle phases.

The attributes that define the two different SOP Instances (Enhanced XA and General ECG) of this example are described in the following figures:

ENHANCED XA SOP INSTANCE
