Vascular noise

Vascular murmur examination is an auxiliary examination method used to check whether blood vessels are normal. Vascular murmurs have arterial and venous murmurs. Arterial murmurs are often in the middle or side of the abdomen. The murmur is caused when the blood flows in the blood vessel, when the blood flow is accelerated, or the blood flow passes through the narrow to a wider place, or the blood flow vortexes the blood flow through abnormal channels, causing the blood vessel wall to vibrate. Through this examination, you can determine the lesion site and the corresponding symptoms.
