Examining the Light Heart Mobile Device App for Assessing Human Pulse Interval and Heart Rate Variability: Validation Study

Examining the Light Heart Mobile Device App for Assessing Human Pulse Interval and Heart Rate Variability: Validation Study

These single metrics conceal beat-by-beat data and prevent researchers from examining raw data points that may skew aggregate indices or be used to calculate several time- and frequency-domain indices of HRV. As a result, researchers may be limited in their ability to obtain beat-by-beat pulse interval data in real-world studies. Furthermore, there is a reported lack of rigor in evaluating apps that measure heart rate or HRV [17].
