DEVICE FOR CALCULATING SYSTOLIC BLOOD PRESSURE USING PULSE TRANSIT TIME AND METHOD THEREFOR

The present invention relates to a device for calculating systolic blood pressure using pulse transit time and a method therefor. A systolic blood pressure calculating method according to the presentinvention comprises the steps of: receiving an input of data regarding pulse transit time (PTT) and systolic blood pressure (SBP) of a patient group; applying the data regarding PTT and SBP of the patient group to a PTT-SBP relationship (SBP=a*PTT-1+y0) and then analyzing the result, thereby extracting a correlation between the parameters (a, y0); receiving an input of data regarding PTT and SBP of a subject; and applying the correlation between the parameters and the data regarding first PTT and SBP of the subject to the PTT-SBP relationship (SBP=a*PTT-1+y0), thereby acquiring the subject's unique parameter values (a, y0). According to the present invention, as described above, in the complete absence of prior information regarding the subject, such as body measurement information, disease information, and demogr
