What heart rate characterizes bradycardia?

• A. Less than 50 beats per minute
• B. Normal heart rate of 60-100 beats per minute
• C. Less than 60 beats per minute
• D. More than 100 beats per minute

Answer: (C)

Bradycardia is defined as a slower than normal heart rate, specifically categorized as having a resting heart rate of fewer than 60 beats per minute. This condition can be a normal physiological response in certain individuals, especially athletes or during sleep, but may also indicate underlying health issues in others. A heart rate under 60 can lead to inadequate blood flow to tissues and organs, potentially resulting in symptoms such as fatigue, dizziness, or even syncope in some cases. Understanding this range is vital for recognizing when bradycardia may be a clinical concern.
