Examining Interbeat Interval Measurement Capability of Wearable Health-Monitoring Algorithms

By: Maxim Integrated Algorithms Team


Photoplethysmography- (PPG-) based heart-rate (HR) monitors are becoming a real option for consumer use, not only for HR monitoring while exercising, but also for measuring other health and wellness indicators such as sleep quality, stress, sports recovery, and so on. PPG provides a more comfortable solution, as it does not require electrodes to be placed on the body. Most of these analyses require heart beat as well as the time interval between heart beats termed as interbeat interval (IBI). This paper examines the IBI measurement capability of Maxim Integrated's wearable health-monitoring algorithms. The evaluation covers different types of datasets collected from several subjects during several resting states, and it evaluates IBI measurement from PPG.
