Genesis of Pistol-Shot and Korotkoff Sounds

Observations on vascular sounds: the pistol-shot sound and the Korotkoff sound.

The similarity between spontaneous "pistol-shot" sounds heard over large vessels and the Korotkoff sounds heard distal to a partially inflated blood pressure cuff suggests that a similar mechanism is responsible for their occurrence. Simultaneous records of intravascular pressures and of the sounds demonstrate that the sounds generally precede the major rise in intravascular pressure. These obs...

The significance of the intermediate Korotkoff sounds.

Except for those sounds that mark the systolic and diastolic blood pressure levels, the murmurs (luring sphygmomanometry are generally ignored. Our studies suggest that the intensity and duration of these murmurs provide an appraisal of the blood flow into the part beyond the cuff under certain conditions. T HE sounds heard at the brachial artery distal to the point of compression by the sphygm...

Korotkoff Sounds - The Improbable also Occurs

Very few discoveries have had such a large impact on and relevance to clinical medicine as the noninvasive measurement of the diastolic blood pressure. A number of gifted physiologists and clinicians were ineffectively in search of a noninvasive method to determine the diastolic pressure. Nonetheless, the quantification of the diastolic BP was not achieved by any of these clinical or physiologi...

A universal celebration: 100 years of Korotkoff sounds, 1905 - 2005.

The measurement of systolic and diastolic blood pressure by auscultation was first described 100 years ago, when a young Russian army doctor, Nicolai Sergeevich Korotkoff, addressed a meeting at the Medical Academy of St. Petersburg on 8th November 1905. During the last hundred years, Korotkoff's contribution has proved to be one of the most useful methods in the diagnosis, treatment, monitorin...
