Related to arrhythmic: arhythmic, dysrhythmic


(ă-ridh'mik, ā-),
Marked by loss of rhythm; pertaining to arrhythmia.


Etymology: Gk, a, rhythmos, without rhythm
pertaining to an absence or irregularity of normal rhythm in the heart's beating.


Marked by loss of rhythm; pertaining to arrhythmia.


(a?rith'me-a) [ ¹an- + rhythm + -ia]
Irregularity or loss of rhythm, esp. of the heart. See: dysrhythmiaarrhythmic (-mik), adjective

atrial arrhythmia

A disturbance in cardiac rhythm, including atrial fibrillation, atrial flutter, multifocal atrial tachycardia, paroxysmal supraventricular tachycardia, and premature atrial contractions.

cardiac arrhythmia

An abnormal rhythm of the heart caused by physiological or pathological disturbances in the discharge of cardiac impulses from the sinoatrial node or their transmission through conductive tissue of the heart.
bradycardia; cardioversion; artificial cardiac pacemaker; sick sinus syndrome; tachycardia;

reperfusion arrhythmia

Cardiac arrhythmia that occurs as the infarcted heart is resupplied with blood after angioplasty or thrombolysis.

sinus arrhythmia

Cardiac irregularity marked by variation in the interval between sinus beats and evident on the electrocardiogram as alternately long and short intervals between P waves. Sinus arrhythmia may occur with respiration (evidenced as an increased heart rate during inspiration and a decreased heart rate on expiration) or may result from the use of digitalis glycosides. In older patients, presence of sinus arrhythmia is common and is statistically linked with an increased risk of sudden death.

ventricular arrhythmia

A disturbance of the (cardiac) ventricular rhythms, including torsades de pointes, ventricular fibrillation, ventricular flutter, ventricular tachycardia, or frequent premature ventricular contractions.
Synonym: ventricular dysrhythmia

RESEARCH funded by the charity Cardiac Risk in the Young (CRY) has highlighted that more than 80% of cases of young sudden arrhythmic death (SADS) between the ages of 18 and 35 occur during sleep or at rest - a much higher proportion than those who die playing sport at either an elite or grass roots level.

The use of implantable cardioverter defibrillator (ICD) in heart failure patients decreases the arrhythmic mortality with the cost of increasing the number of patients to be treated, and microvolt T-wave alternans (MTWA) testing can be used as a good criteria to better select the candidate for such a therapy.
