Cardiovascular Signals in Photoplethysmography: Heart Health from the Wrist
Wearable sensors provide the opportunity for continuous passive monitoring of health indicators. In particular the heart rate sensors can extract the pulse waveform; and that waveform can be mined for heart health indicators. At present wearable devices only mine for the heart rate; but there's a lot of cardiovascular activity that affects its shape.
