Which term describes a heart rhythm disorder characterized by abnormal rhythm?

Explanation:
Think of heart rhythm disorders in terms of the heartbeat pattern. The prefix dys- means abnormal or faulty, and rhythm is the heartbeat pattern. Put together, dysrhythmia literally means an abnormal rhythm, which describes a rhythm disturbance of the heart. That specificity makes it the best term for a heart rhythm disorder characterized by abnormal rhythm. Note that arrhythmia is a closely related term used for an abnormal rhythm as well, but the form with dys- emphasizes the abnormal rhythm idea directly. Ischemia refers to reduced blood flow, not rhythm, and a semicolon is unrelated.
