A system (1) for detecting vital physiological parameters of a subject (10), comprising support means (15) which can be associated with the subject (10) and are connected to acquisition means (20) configured to acquire synchronously an ECG signal and a PPG signal of the subject (10)； the system (1) comprises processing means (40) which are connected to the acquisition means (20), the processing means (40) comprising a systolic and diastolic arterial pressure module (43) configured to calculate a vital physiological parameter related to systolic and diastolic arterial pressure, which can be transmitted to at least one telematic device (5) by way of transceiver means (60) configured to transmit the vital physiological parameter toward the telematic device (5).
