Still's murmur is detected via auscultation with a stethoscope.It has a peculiar "musical", "resonant" or "vibratory" quality that is quite unique. [1] [2] It is generally most easily heard at the left middle or lower sternal border and the right upper sternal border, often with radiation to the carotid arteries, although other locations are common.
The humming may be confused with a heart murmur, which may be a symptom of a potentially serious condition. The difference is easily detected by placing light pressure on the internal jugular vein when listening to the heart, which will immediately abolish or change the venous hum, whereas a true heart murmur will be unaffected by this maneuver.
Venous hum: Infraclavicular throughout the cardiac cycle (right side > left side), diminishes with jugular vein palpation or neck turning PDA: Supraclavicular arterial bruit (Systemic Flow Murmur) Above clavicles: aortic stenosis, bicuspid aortic valve: Peripheral pulmonary stenosis (Pulmonary flow murmur) High-pitch with radiation to back and ...
Bruit, also called vascular murmur, [3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.

Venous insufficiency is the most common disorder of the venous system, and is usually manifested as either spider veins or varicose veins. Several treatments are available including endovenous thermal ablation (using radiofrequency or laser energy), vein stripping , ambulatory phlebectomy , foam sclerotherapy , laser , or compression.
Even when he travelled 12,000 miles from his Cambridgeshire home to New Zealand, he could still hear it. It wreaked such havoc on his life, he had to quit his job. He became increasingly isolated ...
It may occur as the result of carotid artery stenosis [1] (though some disagree); [2] however, most carotid bruits, particularly those found in younger or asymptomatic patients, are not related to any disease and are termed "innocent carotid bruits". [3] Many carotid bruits are discovered incidentally in an otherwise asymptomatic patient. The ...
