Which of the following rhythms typically indicates bradycardia?

• A. A heart rate less than 60 beats per minute
• B. A heart rate between 60-100 beats per minute
• C. A heart rate greater than 100 beats per minute
• D. A heart rate that is irregularly irregular

Answer: (A)

A heart rate less than 60 beats per minute is typically indicative of bradycardia. Bradycardia is defined as a slower than normal heart rate, which can be a result of various factors including increased vagal tone, medication effects, or underlying medical conditions. In adults, a resting heart rate below 60 beats per minute is recognized as bradycardia and may lead to symptoms such as fatigue, dizziness, or syncope if the heart rate is significantly low. Understanding heart rate classifications is essential for recognizing cardiac conditions and assessing the patient's cardiovascular status. A heart rate that falls between 60-100 beats per minute is considered normal, while rates exceeding 100 beats per minute suggest tachycardia, and an irregularly irregular heart rate points towards conditions like atrial fibrillation rather than bradycardia.
