arrhythmia; cardiac arrhythmia

Hypernyms ("cardiac arrhythmia" is a kind of...):

cardiopathy; heart disease (a disease of the heart)

Hyponyms (each of the following is a kind of "cardiac arrhythmia"):

flutter (abnormally rapid beating of the auricles of the heart (especially in a regular rhythm); can result in heart block)

cantering rhythm; gallop rhythm (cardiac rhythm characterized by the presence of an extra sound; can indicate a heart abnormality)

atrial fibrillation (fibrillation of the muscles of the atria of the heart)

bradycardia (abnormally slow heartbeat)

Adams-Stokes syndrome; atrioventricular block; heart block; Stokes-Adams syndrome (recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat)

premature ventricular contraction; PVC (irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation)

tachycardia (abnormally rapid heartbeat (over 100 beats per minute))

ventricular fibrillation (fibrillation of heart muscles resulting in interference with rhythmic contractions of the ventricles and possibly leading to cardiac arrest)

(Chloroform, NCI Thesaurus)

Imbalances can cause serious physiologic effects, including seizures, cardiac arrhythmias and convulsions.

(Electrolytes, NCI Thesaurus)

A small medical device generating electrical impulses which is programmed to detect and treat cardiac arrhythmias by delivering electrical energy when indicated.

(Cardioverter-Defibrillator, NCI Thesaurus)

Clinical presentation may include cardiac arrhythmia, cyanosis, heart failure or sudden death.

(Cardiac Fibroma, NCI Thesaurus)

(Budotitane, NCI Thesaurus)

Agents used for the treatment or prevention of cardiac arrhythmias; they may effect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers.
