The present invention relates to a monitoring system (10) for monitoring the hemodynamic status of a subject (100) comprising an imaging unit (12) for obtaining a plurality of images of the subject (100) over time, a sensor unit (14) for acquiring a sensor signal of the subject (100) related to a vital sign of the subject (100), a PPG unit (16) for generating a photo-plethysmography, PPG, signal from said plurality of images, and an evaluation unit (18) for commonly evaluating said sensor signal and said PPG signal to extract one or more pulse arrival time, PAT, measures and to extract a hemodynamic information about the hemodynamic status of the subject (100) from said one or more PAT measures.
