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: -Echocardiogram. This is the main test used to determine the cause of a heart murmur. An echocardiogram uses sound waves to create pictures of the beating heart. It shows how blood flows through the heart and heart valves.

Detailed explanation-3: -Murmurs are described using the thoracic cage position where they are auscultated, pitch, volume, and in which phase of the cardiac cycle they occur. Auscultating other locations such as the axilla and carotid arteries also help accurately diagnose the murmur.

Detailed explanation-4: -You can’t hear a heart murmur with your ear. You need a stethoscope, which makes the sounds loud enough to hear. Healthcare providers classify murmurs by how intense or loud they are.

Detailed explanation-5: -Doppler ultrasound cardiotocography (CTG) is suitable for the assessment of the fetal heart rate and some derived parameters, but it is inadequate for detecting heart murmurs.
