1. A method for measuring a blood pressure, comprising:
- calculating a pulse transit time (PTT) based on a subjects electrocardiogram and pulse wave;
calculating a first systolic pressure based on the PTT, andcalculating a first diastolic pressure by applying, to an equation of regression, the first systolic pressure, the PTT, pulse analysis information for the measured pulse wave, the subject'"'"'s body information inputted by the subject, and environment information together measured when measuring the electrocardiogram and the pulse wave.

Abstract
Disclosed are an apparatus and method for measuring a blood pressure capable of enhancing accuracy and reliability for a blood pressure. According to the apparatus and method, a blood pressure is obtained by using a pulse transit time (PTT) calculated based on a pulse wave measured with a minimized error, a subject'"'"'s body information, pulse analysis information, and environment information together measured when measuring the pulse wave.
