What does bradycardia refer to?

Bradycardia refers specifically to a slower than normal heart rate, which is defined as being below 60 beats per minute. This condition can be a physiological response in some individuals, such as athletes, or it may indicate an underlying health issue that requires attention. Understanding the significance of heart rate measurements is crucial in the interpretation of EKGs, as bradycardia may be asymptomatic or may present with symptoms like fatigue, dizziness, or syncope, depending on the underlying cause. Recognizing bradycardia helps in evaluating cardiac function and deciding on necessary interventions if symptomatic or pathological.
