What does the term "bradycardia" refer to?

Bradycardia refers to a slower than normal heart rate, typically defined as a resting heart rate of less than 60 beats per minute in adults. This condition can result from various physiological processes, such as increased vagal tone, certain medications, or underlying cardiac issues. It is essential to recognize bradycardia because while it can be a benign finding in well-trained athletes or during sleep, it can also indicate potential pathology requiring further evaluation and management, particularly if it leads to symptoms like dizziness, fatigue, or syncope. The understanding of this term is crucial in clinical practice, as heart rate abnormalities can significantly affect a patient's health status.
