System and method for the measurement of arterial pressure through the effects thereof comprising a procedure having six phases and three means; the procedure for indirect-method measurement of diastolic arterial pressure controls the activities of a first means which applies measured gradual external contact force, a second arterial manifestation sensor means which records arterial manifestation, and a third means which is a means of measurement and detection of the diastolic and systolic period of the arterial cycle to generate the value of diastolic arterial pressure by indirect method. Furthermore, systolic arterial pressure is measured without overpressure through the cardiac beats generated subsequent to arterial occlusion.
