Detailed Description

Heart rate variability sensor event data.

Field Documentation

int32_t* beatPos

The count of each heartbeat occurrence depending on the EKG sampling rate.

int32_t bpm

Heart rate measurement.

Beats per minute.

int32_t feature_type

An indicator to heart rate variability monitor output parameters.

If feature_type is 0, beatPos outputs the count of each heartbeat occurrence.

int32_t HF

ECG autonomic nervous system high frequency band.

The output value needs to be divided by 1000.

int32_t LF

ECG autonomic nervous system low frequency band.

The output value needs to be divided by 1000.

int32_t LF_HF

The balance of autonomic nervous system, represented by low frequency band to high frequency band ratio.

The output value needs to be divided by 1000.

int32_t numBeatPos

The total number of the counts.

int32_t SDNN

Standard deviation of ECG normal to normal beat interval.

The output value needs to be divided by 1000

int32_t status

Quality of the measurement, subject to fusion algorithm design.
