Venous hum is a benign phenomena, which is caused by blood flow over jugular veins.^[1]
At rest approximately 20% of Cardiac out put pass through internal carotid and vertebral bodies.
It may result in a continuous humming noise.
Typically it is heard in upper chest near clavicle.
It can be differentiated from cardiac murmurs only by placing a finger on jugular vein which abolish or change the murmur however cardiac born murmurs will not change by this maneuver.
the murmur is also position dependent and can change in intensity if the patient lies in supine form or turn their head to one side.^[2]
