The term "heart sounds" refers to the audible noises that the heart makes as it beats. These sounds provide important clinical information about the function of the heart. Although "heart sounds" is the most commonly used term, there are several synonyms that are often used interchangeably. Some of these synonyms include cardiac sounds, heart murmurs, heartbeats, and cardiac rhythm. Each of these terms is used in different contexts and for different purposes. For example, heart murmurs are abnormal sounds that can indicate a heart problem, while cardiac rhythm refers to the regularity of the heartbeat. Regardless of the terminology used, understanding heart sounds is essential for any healthcare professional involved in cardiac care.
