ANATOMY

Detailed explanation-1: -Heart murmurs are sounds-such as whooshing or swishing-made by rapid, choppy (turbulent) blood flow through the heart. The sounds can be heard with a device called a stethoscope. A typical heartbeat makes two sounds like “lubb-dupp” (sometimes described as “lub-DUP") when the heart valves are closing.

Detailed explanation-2: -A murmur is caused by turbulent or abnormal blood flow across your heart valves. If blood is flowing more rapidly than normal, it can cause an innocent heart murmur (also called normal or physiologic).

Detailed explanation-3: -The “murmur” is the sound of blood flowing. It may be passing through an abnormal heart valve, for instance. Or it may be that a condition makes your heart beat faster and forces your heart to handle more blood quicker than normal.

Detailed explanation-4: -The most common type of heart murmur is called functional or innocent. An innocent heart murmur is the sound of blood moving through a healthy heart in a normal way.

Detailed explanation-5: -Systolic murmur. This happens during a heart muscle contraction. Diastolic murmur. This happens during heart muscle relaxation between beats. Continuous murmur. This happens throughout the cardiac cycle.
