car·di·ac dys·rhyth·mi·a

any abnormality in the rate, regularity, or sequence of cardiac activation.

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.

cardiac arrhythmia

Cardiology Any defect in the heart's electrical activity, which may be detectable only by EKG, or manifest as an abnormality in rate, rhythm, or sequence of cardiac events Clinical From asymptomatic to palpitations, syncope, etc
