Which heart rate range indicates bradycardia on an EKG?

• A. 60 - 100 beats per minute
• B. Below 60 beats per minute
• C. Above 100 beats per minute
• D. 70 - 80 beats per minute

Answer: (B)

Bradycardia is defined as a slower than normal heart rate, specifically when the heart rate is less than 60 beats per minute. This condition can be identified on an EKG by observing the number of QRS complexes that are produced per minute. A heart rate below this threshold indicates that the heart is not beating fast enough, which may reflect underlying medical issues or can be a result of various physiological conditions, including increased vagal tone, certain medications, or pathologies affecting the heart's conduction system. Therefore, identifying a heart rate of below 60 beats per minute as a marker for bradycardia is critical in both clinical assessment and interpretation of EKG results.
