Which term describes abnormal rhythm of the heart?

Explanation:
Abnormal rhythm of the heart is called arrhythmia. This term covers any deviation from the normal, regular sinus rhythm, whether the heartbeat is too fast, too slow, or irregular. The phrase that literally means an abnormal rhythm matches this term. Other options describe different cardiac issues: a moving clump of platelets is a thrombus or embolus, chest pain from low oxygen is angina, and difficulty breathing while lying down is orthopnea.
