“…Their study used high speed video recording (420 fps) to capture 1-min videos between/before/after exercise protocols, with the subject seated and hand on a table. Other studies utilizing PTT to estimate BP from single channel processing include: Yoshioka et al ( 46 ), Huang et al ( 50 ), Khong et al ( 51 ), Murakami et al ( 44 ) and Shirbani et al ( 57 ). As an alternative to PTT, it may be possible to capture videos of hands at different heights, relating the difference in pulse amplitudes between the hands to BP ( 58 ).…”

Regular blood pressure (BP) monitoring enables earlier detection of hypertension and reduces cardiovascular disease. Cuff-based BP measurements require equipment that is inconvenient for some individuals and deters regular home-based monitoring. Since smartphones contain sensors such as video cameras that detect arterial pulsations, they could also be used to assess cardiovascular health. Researchers have developed a variety of image processing and machine learning techniques for predicting BP via smartphone or video camera. This review highlights research behind smartphone and video camera methods for measuring BP. These methods may in future be used at home or in clinics, but must be tested over a larger range of BP and lighting conditions. The review concludes with a discussion of the advantages of the various techniques, their potential clinical applications, and future directions and challenges. Video cameras may potentially measure multiple cardiovascular metrics including and beyond BP, reducing the risk of cardiovascular disease.
