  • Wearable photoplethysmography device for detecting clinical decompensation based on heart rate variability
    Patent number: 12690775
    Abstract: Disclosed are clinical decompensation monitoring platforms and methods. An example platform includes a wearable device to acquire photoplethysmography (PPG) waveform data representing a person's heart rate variability (HRV). Also disclosed are methods for collecting and verifying the HRV data, scoring and selecting optimal segments of HRV data for further processing that entails detecting clinically significant changes in a high frequency (HF) component, and passively monitoring clinical decompensation for providing patient feedback with individualized coping mechanisms.
    Type: Grant
