| Rows 1-3: | Show circumferential strain for the left ventricle base, mid, and apex regions. | | Row 4: | Shows circumferential strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT. | | Row 5: | Shows global circumferential strain. | | Rows 6-8: | Show longitudinal strain for 4 chamber, 3 chamber, and 2 chamber views. | | Row 9: | Shows longitudinal strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT. | | Row 10: | Shows global longitudinal strain. |

|
- CVORRES: Result of the measurement or finding as originally received or collected.
- CVORRESU: Original units in which the data were collected. Unit for CVORRES.
- CVSTRESC: Result value for all findings from CVORRES in a standard format or in standard units. If results are numeric, they should also be stored in numeric format in CVSTRESN.
- CVSTRESN: Used for continuous or numeric results or findings in standard format; copied in numeric format from CVSTRESC.
- CVSTRESU: Standardized units used for CVSTRESC and CVSTRESN.
- CVLOBXFL: Last Observation Before Exposure Flag. Operationally-derived indicator used to identify the last non-missing value prior to RFXSTDTC. The value should be "Y" or null.
