Standard HBR methods (PPG, ECG, oscillometric) remain in use; leaves open comparative performance across clinical settings.
This review outlines the historical evolution and technological advancements of heart rate measurement techniques, emphasizing the potential of non-contact photoplethysmography for remote healthcare monitoring.
Khong et al. (2021) conducted a review in Heart beat rate measurement. Heart beat rate measurement techniques was evaluated. Non-contact photoplethysmography imaging provides the advantage of excluding direct sensor contact for heart beat rate measurement, though motion artifacts remain a critical challenge.
