Korotkoff method is a non-invasive auscultatory technique for determining both systolic and diastolic blood pressure levels.
The method requires а sphygmomanometer and а stethoscope.
Due to ease and accuracy, it is considered a "gold standard" for blood pressure measurement
Korotkoff sounds are pulse-synchronous circulatory sounds heard through the stethoscope in auscultation of blood pressure using Riva-Rocci's sphygmomanometer.

Korotkoff test or Korotkoff sign is a collateral circulation test: in aneurysm, if the blood pressure in the peripheral circulation remains fairly high while the artery above the aneurysm is compressed, the collateral circulation is good.
