Bradycardia is defined as which of the following?

Explanation:
Bradycardia means a slower-than-normal heart rate. In adults, a resting heart rate below about 60 beats per minute defines bradycardia. This is distinct from tachycardia, which is a fast heart rate, and from an irregular heartbeat, which describes a rhythm problem (arrhythmia). A normal heart rate is not bradycardia. Sometimes a slow rate is normal, especially in well-trained athletes, but if symptoms like dizziness, fatigue, or fainting occur, it may indicate underlying issues that need evaluation.
