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.
