Abnormal heart sounds are noises that occur during the heartbeat cycle, which can indicate underlying health issues. These sounds may include murmurs, gallops, or snaps, and are often detected using a stethoscope during a physical examination. They can result from various factors, such as valve problems, congenital heart defects, or increased blood flow. Healthcare professionals assess these sounds to determine their significance. For instance, a murmur may suggest turbulent blood flow, while a gallop could indicate heart failure. Identifying abnormal heart sounds is crucial for diagnosing and managing cardiovascular conditions effectively.
