Abstract: Various embodiments of systems and methods for tracking ballistocardiogram, photoplethysmogram, blood pressure and abnormal heart rhythm based on optical imaging of a human body are disclosed. Ballistocardiogram and photoplethysmogram signals from a similar region of the human body are simultaneously obtained, and the time delay between the two signals is used to determine the blood pressure of the subject, together with other physiological parameters of the subject, including gender, age, weight, height, heart rate, stroke volume, blood pressure and abnormal heart rhythm obtained using other methods.
