Resource Profile: ECG QT Interval

Defining URL:https://www.napkon.de/fhir/StructureDefinition/ecg-qt-interval
Version:1.0.0
Name:ECGQTInterval
Title:ECG QT Interval
Status:Active as of 2021-11-17
Definition:

QT Interval duration from electrocardiogram

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

The official URL for this profile is:

https://www.napkon.de/fhir/StructureDefinition/ecg-qt-interval

Guidance

This profile encodes the QT interval from electrocardiography (ECG) waveforms.

Parameter Case Report Form Response Options
QT Interval Normal / Prolonged / Shortened

The response options are encoded as follows:

Response Option Observation.valueCodeableConcept
Normal Electrocardiogram: Q-T interval normal (finding)
Prolonged Prolonged QT interval (finding)
Shortened Shortened QT interval (finding)

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