ARRHYTHMIA
Pronunciation (US): | (GB): |
I. (noun)
Sense 1
Meaning:
An abnormal rate of muscle contractions in the heart
Synonyms:
arrhythmia; cardiac arrhythmia
Classified under:
Nouns denoting stable states of affairs
Hypernyms ("arrhythmia" is a kind of...):
cardiopathy; heart disease (a disease of the heart)
Hyponyms (each of the following is a kind of "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)
Derivation:
arrhythmic (lacking a steady rhythm)
Context examples:
An electrocardiographic finding of a supraventricular arrhythmia characterized by 3 or more distinct P wave morphologies with an isoelectric baseline, variable PR intervals and no predominant atrial rhythm.
(Multifocal Atrial Tachycardia by ECG Finding, NCI Thesaurus/CDISC)
An electrocardiographic finding of an arrhythmia originating from within the atrioventricular node.
(Nodal Arrhythmia by ECG Finding, NCI Thesaurus)
Clinical signs and symptoms include cyanosis that is present at birth, poor growth, dyspnea, tachypnea, arrhythmia, cardiomegaly, and heart failure.
(Persistent Truncus Arteriosus, NCI Thesaurus)
A invasive therapeutic procedure to destroy the tissue in the cardiac atria that is the source of an arrhythmia.
(Atrial Ablation, NCI Thesaurus)
An invasive therapeutic procedure to destroy tissue in the AV-node that contributes to an arrhythmia.
(Ablation of Cardiac Atrioventricular Node, NCI Thesaurus/ACC)
Having stabilizing and quinidine-like effects on cardiac rhythm, Acebutolol is used in ventricular arrhythmias.
(Acebutolol, NCI Thesaurus)
Clinical manifestations in infancy include cardiomyopathy, arrhythmias, hypotonia, and hepatomegaly.
(Acyl-CoA Dehydrogenase, Very Long-Chain Deficiency, NCI Thesaurus)
An invasive therapeutic procedure to destroy tissue in an accessory pathways in the atrioventricular conduction system that contributes to arrhythmia.
(Ablation of Cardiac Accessory Pathway, NCI Thesaurus/ACC)
The most common type of arrhythmia, atrial fibrillation is an irregular beating of the heart that can lead to stroke, blood clots, or heart failure if left unchecked.
(Heart-Checking App May Help Prevent Strokes, The Titi Tudorancea Bulletin)
Patients who are diagnosed with atrial fibrillation/arrhythmias (a quivering or irregular heartbeat) are often advised to avoid caffeine.
