Bradycardia is defined as:

Bradycardia is characterized by a pulse rate that is slower than the normal range, specifically defined as a heart rate below 60 beats per minute (bpm). This lower heart rate can indicate various underlying conditions, including heart disease, electrolyte imbalances, or it may be a normal finding in well-conditioned athletes. Understanding this definition is important for healthcare professionals, as bradycardia can affect an individual's cardiac output and overall health.

While a pulse rate over 100 bpm is classified as tachycardia, and rates between 60 to 100 bpm are typically considered normal, a pulse rate around 80 bpm falls within the normal range but does not signify bradycardia. Therefore, recognizing that bradycardia specifically refers to rates below 60 bpm is crucial for proper assessment and intervention in clinical settings.
