Which term means abnormal heart rhythm?

• A. Thrombophlebitis
• B. Arrhythmia
• C. Leukemia
• D. Cardiologist

Answer: (B)

Abnormal heart rhythm is called an arrhythmia. The heart beats in a regular pattern because its electrical system coordinates each beat. When those electrical signals are faulty, the timing or pattern changes, producing a rhythm that is too fast, too slow, or irregular. That precise idea is captured by the term arrhythmia, which labels any disruption in the heart’s rhythm. For example, variations like atrial fibrillation or other rhythm disturbances fall under this umbrella, reflecting the core meaning of the word. The other terms refer to entirely different concepts: thrombophlebitis is inflammation with clotting in a vein, leukemia is a cancer of blood-forming tissues, and a cardiologist is a physician who specializes in heart disease, not a rhythm abnormality.
