ATachycardia
BBradycardia
CAsystole
DFibrillation
Answer & Solution
Correct answer: B. Bradycardia
1. Normal resting heart rate in an adult falls in the range of 60 to 100 bpm.
2. A resting heart rate below this range, under 60 bpm, is termed bradycardia.
3. A resting rate above 100 bpm, by contrast, is termed tachycardia.
4. Asystole refers to complete cessation of electrical activity, and fibrillation refers to uncoordinated beating, neither of which is simply defined as a resting rate below 60 bpm.
