Prev | Stress Testing Report Templates | Next

### TID 3304 Stress Test Measurement Group

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 exam 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 Measurements” 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 Measurements” 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°
