Murmurs are:

• A. Abnormal Heart Sounds
• B. Blood Blocks Flow of a Vein
• C. Dialated, Swollen Veins That Have Lost Their Elasticity and Cause Stasis
• D. Inflammation of the Pericardium

Answer: (A)

Murmurs are abnormal heart sounds caused by turbulent blood flow within the heart or across a valve. This turbulence alters the normal sound produced by the heart, creating a swishing or whooshing noise heard with a stethoscope. Murmurs can occur during different parts of the cardiac cycle and may be innocent or indicate underlying valvular disease, congenital defects, or other heart conditions that affect flow. The other descriptions refer to conditions outside of producing heart sounds: a blockage in a vein is a thrombus that obstructs flow, varicose veins are dilated superficial veins due to venous insufficiency, and inflammation of the pericardium produces a friction rub, which is a different type of abnormal heart sound.
