Which health concept is associated with an abnormal heart rhythm characterized by quivering?

• A. Fibrillation
• B. Tachycardia
• C. Hypertension
• D. Arrhythmia

Answer: (A)

Quivering heart rhythm is called fibrillation. When the heart’s electrical signals don’t coordinate the chambers, the muscle quivers instead of squeezing in a unified beat. This rapid, irregular motion disrupts effective pumping, which is why fibrillation is such a serious rhythm disturbance. Tachycardia describes a fast heart rate that may still be organized, hypertension is about high blood pressure, and arrhythmia is a broad term for any abnormal rhythm. The specific pattern of a quivering, unsynchronized rhythm points to fibrillation.
