Resource Profile: Heart Rate

Official URL: http://hl7.org/fhir/us/vitals/StructureDefinition/heart-rate Version: 2.0.0
Draft as of 2024-10-09 Computable Name: HeartRate

The number of heart beats in a minute.

Scope

The Heart Rate profile contains one observation, heart rate. In addition, this profile contains the following qualifying observations with associated SNOMED CT value sets: Body Position, observation-deviceCode, Exercise Association, SleepStatus, and MeasurementSetting.

Note

Many times Heart Rate is measured at the same time as a blood pressure, using a blood pressure device. Although this profile does not constrain the Observation.device element to the Blood Pressure Device profile as we did for the blood pressure profiles, it may be used to record the blood pressure device used to obtain the heart rate. This constraint was not made due to the fact that there are many devices primarily used for other measurements (e.g. blood pressure, oxygen saturation via pulse oximetry) that could also measure a heart rate. Constraining Observation.device to Blood Pressure Device would falsely limit it.

Examples

The following examples are provided to illustrate conformant resource content to this profile.

Value sets

Value Set Purpose
Body Position value set This value set contains concepts used to result the patient's body position, referencing the SNOMED Code 397155001 Body position (observable entity) and the LOINC term "Body position with respect to gravity" 8361-8.
Heart Rate Device Type value set This value set contains concepts used to result the type of device used to measure a heart rate, referencing the LOINC term "Type of Heart rate device" 8887-2.
Heart Rate Measurement Body Location Precoordinated value set This value set contains a constrained list body location values used to result the body location where a heart rate was measured, referencing the LOINC term "Heart rate measurement site", 41904-4.
Heart Rate Measurement Method value set This value set contains concepts used to result the method used for a blood pressure measurement, referencing the LOINC term "Heart rate method” 8886-4.
Exertion Phase value set The purpose of the value set is to document exercise associated with a measurement. Resulting LOINC code 74008-4 "Exercise intensity".
Sleep Status value set This value set contains values used to indicate the state of wakefulness during measurement
