What term describes an abnormally slow heartbeat?

Bradycardia is the term that describes an abnormally slow heartbeat. This condition is diagnosed when the resting heart rate falls below the normal range of 60 beats per minute in adults. Bradycardia can be caused by various factors, including aging, certain medications, or underlying medical conditions affecting the heart's electrical system. In some cases, it may not present any symptoms; however, a significantly low heart rate can lead to fatigue, dizziness, or fainting, necessitating medical evaluation.

Understanding this term is important, especially in sports medicine, where monitoring heart rates can help assess an athlete's cardiovascular fitness and overall health. Recognizing bradycardia can be crucial in sports settings to ensure athletes are fit and safe for physical activity.
