What term is used to describe extra heart sounds?

• A. Edema
• B. Murmur
• C. Tachycardia
• D. Ischemia

Answer: (B)

The term "murmur" is specifically used to describe abnormal heart sounds that are typically caused by turbulent blood flow within the heart. These sounds can be heard with a stethoscope during a heartbeat and may indicate various cardiac conditions or abnormalities, such as valve problems or congenital heart defects. Murmurs are classified based on their timing during the cardiac cycle (systolic or diastolic) and their characteristics (such as location, intensity, and pitch).

In contrast, the other terms refer to different medical phenomena. Edema refers to swelling caused by excess fluid accumulation in tissues, tachycardia means an increased heart rate, and ischemia denotes a reduced blood supply to an organ or tissue, often leading to damage. Thus, "murmur" is the correct term specifically related to the context of extra heart sounds.
