Heart rate measurements can be performed in the Clarius App through three primary methods: Automated Heart Rate, M-Mode measurements, and Pulsed Wave Doppler measurements.
Automated Heart Rate
For Clarius scanners equipped with a cardiac application (currently C3, PA, and PALHD3), the Automated Heart Rate feature can be enabled with the appropriate software license. Once licensed, this feature can be toggled on or off via the Modes menu. During scanning, maintain the anatomical position for approximately 5 seconds to calculate a valid heart rate. If the heart rate cannot be determined, '(--)' will be displayed.
M-Mode Measurement
Turning on M-Mode will allow for the display of the motion mode spectrum, in which a manual heart rate measurement can be made.
Once a proper spectrum has been acquired, the generic heart rate measurement tool can be used to measure by placing 2 calipers on the spectrum. Similarly, the generic time measurement tool can be used to output time instead of frequency.
Pulsed Wave Doppler Measurement
Turning on Pulsed Wave Doppler Mode (requires a valid software license) will allow for the display of the spectral Doppler spectrum, in which a manual heart rate measurement can be made.
Once a proper spectrum has been acquired, the generic heart rate measurement tool can be used to measure by placing 2 calipers on the spectrum. Similarly, the generic time measurement tool can be used to output time instead of frequency.
