Guidance

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

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

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)

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.
