In medical terminology, what does "bradycardia" refer to?

Bradycardia refers to an abnormally slow heart rate, typically defined as a resting heart rate of fewer than 60 beats per minute in adults. This medical term is derived from the Greek words "brady," meaning slow, and "kardia," meaning heart. In clinical settings, bradycardia may indicate various medical conditions, including issues with the heart's electrical conduction system or effects from certain medications. Understanding this term is crucial for healthcare professionals as it helps in diagnosing and managing patients who present with symptoms related to decreased cardiac output or other cardiac concerns. The significance of accurately identifying bradycardia lies in its potential implications for patient health and the need for appropriate intervention.
