cardiac arrhythmia

Etymology: Gk, kardia + a + rhythmos, without rhythm
an abnormal cardiac rate or rhythm. The condition is caused by a failure of the sinus node to maintain its pacemaker function or by a defect in the electrical conduction system. Examples of arrhythmia include bradycardia, ectopic beat, heart block, and tachycardia.
