Synchronous tracings of Korotkov's sounds, electrocardiogram, and pressure in sphygmomanometer cuff make possible to construct a curve whose shape is practically congruent with the ascending limb of the arterial pressure wave; the curve is usable for determining several haemodynamic indicators, namely, the maximal and minimal pulse, and mean pressures, pulse wave propagation velocity, and myocardial contraction capacity. When arterial sounds are objectively recorded with dur regard to the cuff dimensions and adherence to the "ipsilaterality principle", the error of pressure measurement does not exceed 4--5 mmHg.
