Diastolic Kazakh-like noise

Diastolic Kazakh-like murmurs are a type of cardiac murmur. Cardiac murmur refers to the abnormal sound produced by the vibration of the walls of the heart or blood vessels caused by end flow in the heart or blood vessels when the heart contracts or relaxes, in addition to heart sounds and extra heart sounds. Normal blood flow is laminar, and no sound is produced. When the blood flow is accelerated, abnormal blood flow channels or blood flow tube diameters are abnormal, and blood viscosity changes, etc., the laminar flow can be turned into turbulence, or the vortex impacts the heart wall and large blood vessels Walls, valves, chordae, etc. cause it to vibrate and generate noise at the corresponding site.
