| Concept | Left ventricular ejection fraction |
| Description | The volumetric fraction of fluid ejected from the left ventricle with each heartbeat. |
| Use | Use to record the calculated ejection fraction from the left ventricle of the heart. The volume measurements will be recorded in other archetypes, specific for the purpose. Measurements of ejection fraction for the same chamber, but by different modalities, are not interchangeable. |
| Misuse | Not to be used to record the ejection fraction for any anatomical site other than the left ventricle - use the parent archetype OBSERVATION.ejection_fraction for this purpose. |
| Purpose | To record the calculated ejection fraction from the left ventricle of the heart. |

| Modality | Modality: The modality used to measure the ejection fraction volumes. For example: echocardiography; MRI; or nuclear medicine scan. Measurements by different modalities are usually not interchangeable. |
| Equation | Equation: The equation used to calculate the ejection fraction. |
| Extension | Extension: Additional information required to extend the model with local content or to align with other reference models or formalisms. For example: local information requirements; or additional metadata to align with FHIR. Include: All not explicitly excluded archetypes |
| state | |
| Confounding factors | Confounding factors: Issues or factors that may impact on the calculation of ejection fraction, not captured in other fields. |
| data | |
| Chamber | Chamber: The organ or part of organ where the volumes were measured. For example: atrium; left ventricle; gall bladder; leg vein
|
| Specific site | Specific site: Specific anatomical location of volume measurements when identification of the 'Chamber' is not sufficient. For example: identification of specific leg veins. |
| Ejection fraction | Ejection fraction: The calculated volumetric fraction based on volume measurements taken from the identified chamber or specific site. Property: Proportion Units: 0.0..100.0 % |
| events | |
| Any event | Any event: Default, unspecified point in time or interval event which may be explicitly defined in a template or at run-time. |
