Webance of Korotkoff sounds during blood pres-sure cuff deflation in the absence of cardiac arrhythmias) was first recognized by Krylov in 1906,12 1 year after N.S Korotkoff. 3 described the ausculta-tory blood pressure measurement technique. Cook and Taussig4 are generally credited as the first to recognize the clinical importance of these gaps.
WebA widening in the diameter of the artery takes place in the phase II of the Korotkoff sound technique.

WebAn auscultatory gap, also known as the silent gap, [1] is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure. It is associated with reduced peripheral blood flow caused by changes in the pulse wave. [2] The improper interpretation of this gap may lead to blood pressure monitoring errors, [1] [2 ...
