ABSTRACT OF THE DISCLOSURE In systolic pressure determining apparatus utilizing a pressure cuff and means for measuring a fluctuating quantity proportional to the sum of the cuff pressure and the fluctuating component proportioned to the pulsatile blood pressure, and including means for determining the maximum value of the fluctuating component as cuff pressure is varied, the improvement comprising means for converting the quantity into a representation of a time derivative of the fluctuating component, means for obtaining a time integral of the time derivative over an interval of pre- determined limits between initiation of systolic rise and systolic peak in each blood pressure pulse, and means extending the time integral, as a measure of pulse pressure amplitude, to the maximum value determining means. Specif- ically, certain crossings of a reference value by the time derivative are recognized as being the initiation of systolic rise and the systolic peak respectively, and the integration occurs over this interval. The method implemented by the improved means also comprises an aspect of the invention.
