Korotkoff sounds

The second and third Korotkoff sounds have no known clinical significance.

Diastolic is identified at the moment the Korotkoff sounds disappear (fifth phase).

Systolic pressure (first phase) is identified with the first of the continuous Korotkoff sounds.

Korotkoff sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure.

Korotkoff sounds are pulse-synchronous circulatory sounds heard through the stethoscope in auscultation of blood pressure using Riva-Rocci's sphygmomanometer.
