TID 3304 Stress Test Measurement Group

TID 3304 Stress Test Measurement Group (Current)
Prev	Stress Testing Report Templates	Next

Each instance of the Stress Test Measurement Group represents a group of data elements acquired at approximately the same instant, and conventionally rendered as row in a tabular presentation. It is typically generated during the Stress study whenever a time interval elapses (for example, every minute of the phase), when a technician observes data worth capturing, or when measurements exceed a given range.

Type:: Extensible
Order:: Significant
Root:: No

Content Item Descriptions

Row 1	The Container shall have a specific Content Item Observation DateTime (0040,A032) Attribute to indicate the time at which the measurements were made.
Row 10	Included TID 3106 “Drugs/Contrast Administered” allows the recording of test medications other than the Pharmacological Stress Agent identified in TID 3301 “Stress Test Procedure Description”.
Rows 17, 18	ECG ST elevation/depression is measured in units of mV, but is conventionally reported in units of mm, based on strip recordings with scaling of 100 uV/mm. The display application should render these measurements in units meaningful to the user.
Row 19	Note that the MDC codes for "per lead" measurements specified in CID 3228 “ECG Timing Measurement” are base codes for post-coordination with lead identifiers conveyed in the Target Site modifier in TID 300 “Measurement”. MDC also defines pre-coordinated codes that include both the measurement and the lead, which may be used in this row.
Row 20	Note that the MDC code for "QTc interval per lead" specified in CID 3227 “QTc Measurement” is a base code for post-coordination with lead identifiers conveyed in the Target Site modifier in TID 300 “Measurement”. MDC also defines pre-coordinated codes that include both the measurement and the lead, which may be used in this row. Note that TID 300 “Measurement” enables the encoding of a non-standard correction algorithm, either as a local code, or as a TEXT Method Citation (see TID 300 “Measurement” Row 12).
Row 21	R-R interval used for QT correction algorithm
Row 22	Recommended range for ECG axis measurements is -90° to +270°
