In terms of heart rate, what is considered bradycardia?

Bradycardia is defined as a slower than normal heart rate, specifically categorized as a resting heart rate of less than 60 beats per minute. This condition can result from various factors, including physical fitness levels, certain medications, or underlying health conditions, and can indicate issues such as heart block or other electrical conduction system disturbances in the heart.

A heart rate under 60 beats per minute suggests that the heart may not be pumping blood effectively enough to meet the body's demands, especially during periods of activity. While normal resting heart rates typically range from 60 to 100 beats per minute, falling below this threshold indicates bradycardia. It is essential for healthcare providers to evaluate the underlying cause of bradycardia and to monitor the patient's symptoms, as treatment may be necessary if the bradycardia leads to significant concerns such as dizziness, fatigue, or syncope.
