What does the term "bradycardia" refer to?

Bradycardia refers to a heart rate that is slower than normal, typically defined as a resting heart rate of fewer than 60 beats per minute in adults. This condition can be a normal finding in some individuals, such as athletes who have a well-conditioned cardiovascular system. However, bradycardia can also be indicative of underlying health issues, particularly if accompanied by symptoms like dizziness or fatigue. Understanding bradycardia is essential in nursing practice, as it can influence patient assessment, treatment decisions, and ongoing monitoring.
