摘要：

A method for providing a blood pressure indicator of a person, the method comprises: obtaining multiple first detection signals from a non-invasive optical plethysmography sensor that monitors a body area of the person; obtaining multiple second detection signals from a non-invasive Electrocardiography sensor; processing, by a health monitoring module, the multiple first detection signals to detect first points in time that correspond to arrivals of blood pulses to the body area that is monitored by the non-invasive optical plethysmography sensor; processing the multiple second detection signals to detect second points in time that correspond to peaks of QRS complexes; and calculating at least one blood pressure indicator in response to at least one timing difference between at least a single pair of first and second points in time that are associated with a same heartbeat.
