What term describes a slow heart rate?

Bradycardia is the term used to describe a slow heart rate, specifically when the heart beats fewer than 60 times per minute in adults. Understanding this term is essential in healthcare as it helps professionals monitor patients' cardiovascular health. Bradycardia can occur in healthy individuals during sleep or in highly trained athletes, but it can also indicate underlying health issues, particularly if accompanied by symptoms like dizziness or fatigue. The recognition of bradycardia is crucial for timely medical intervention if necessary.

Tachycardia, on the other hand, refers to a rapid heart rate exceeding 100 beats per minute. Arrhythmia indicates any irregularity in the heartbeat, which can involve both slow and fast rates or abnormal rhythms. Hypertension refers to high blood pressure, which is related to cardiovascular health but is distinct from heart rate terminology. Understanding these definitions is key to recognizing varying heart conditions and their implications on patient care.
