ABSTRACT:
An electronic blood pressure meter which determines a systolic blood pressure value and a diastolic blood pressure value by detecting a sharpest positive peak and a sharpest negative peak of a pulse wave, respectively, which may be extracted from a cuff pressure. The sharpest peaks may be detected by finding the points of intersection of the pulse wave level with a certain threshold level and finding the shortest time interval between adjacent points of intersection interposing a peak therebetween. Since the principle of measurement is exact and can be implemented as a relatively simple algorithm, accurate measurement is possible substantially without any exception.
