systolic blood pressure of the patient in the case of this third preferred embodiment of the electronic blood pressure meter of the present invention is set as being 60 of the maximum pulse wave amplitude value apmax on the high cuff pressure side thereof where said pulse wave amplitude is increasing along with time as the cuff pressure is steadily decreased and the threshold value for said pulse wave amplitude for determining the diastolic blood pressure of the patient is set as being 70 of the maximum pulse wave amplitude value apmax on the low cuff pressure side thereof where said pulse wave amplitude is decreasing along with time as the cuff pressure is steadily decreased and as the compensation equation for the arithmetic compensation operation the following equation 9 is used for the systolic blood pressure here sys is the finally determined value for the systolic blood pressure of the patient while s is the systolic blood pressure value referred to as the systolic pressure value candidate hereinafter as determined by the blood pressure determining means before this arithmetic compensating operation is performed equation 5 is obtained by solving equation a described earlier in this specification in terms of the systolic blood pressure value saus similarly as the compensation equation for the arithmetic compensation operation the following equation 12 is used for the diastolic blood pressure here dia is the finally determined value for the diastolic blood pressure of the patient while d is the diastolic blood pressure value referred to as the diastolic pressure value candidate hereinafter.
