Abstract
An electronic Sphygmomanometer employing both the Korotkoff method and the oscillometric method and thereby capable of accurately measuring the blood pressure due to the two advantages of the above-described methods. The electronic Sphygmomanometer is arranged in such a manner that either of the results of measurements of the two methods can be automatically selected, that the gate for detecting the Korotkoff sound by using the oscillation in cuff pressure is automatically stopped and that the validity of the Korotkoff sound is determined in accordance with the change in the height of the oscillating pulse wave.
