Version:1.0.0
Name:LeftVentricularEjectionFraction
Title:Left Ventricular Ejection Fraction
Status:Active as of 2021-08-10
Definition:

Left Ventricular Ejection Fraction in %

Publisher:Charité - Universitätsmedizin Berlin
Source Resource:XML / JSON / Turtle

The official URL for this profile is: 

https://www.napkon.de/fhir/StructureDefinition/left-ventricular-ejection-fraction

Guidance

This profile encodes the left ventricular ejection fraction (LVEF).

Parameter Case Report Form Response Options
Left ventricular ejection fraction Actual value [%] + Low grade / medium grade / high grade

The grade of the ejection fraction is encoded in Observation.interpration using the following codes from the ObservationInterpretation CodeSystem:

Response Option Observation.interpretation
Low grade #L "Low"
Medium grade #N "Normal"
High grade #H "High"

This profile of a FHIR Observation is derived from the Observation FHIR resource.
