Classified under:
Relational adjectives (pertainyms)
Domain category:
anatomy; general anatomy (the branch of morphology that deals with the structure of animals)
Pertainym:

Derivation:
atrium (any chamber that is connected to other chambers or passageways (especially one of the two upper chambers of the heart))
Context examples:
This is the result of intermittent failure of atrial electrical impulse conduction through the atrioventricular (AV) node to the ventricles.
(AV Block Second Degree Mobitz Type I, NCI Thesaurus/CTCAE)
An electrocardiographic finding of premature atrial complexes which have 2 or more distinct morphologies, suggesting origin at more than one atrial site.
(Multifocal Atrial Premature Complex by ECG Finding, NCI Thesaurus/CDISC)
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 in which both the atrial and ventricular rhythm are controlled by an electrical impulse from an artificial cardiac pacemaker.
(Paced Atrial And Ventricular Rhythm, NCI Thesaurus/CDISC)
Electrocardiographic criteria used for the diagnosis of right atrial abnormality may include a peaked p wave greater than 2.5 millimeters in amplitude in the inferior leads.
(P-pulmonale by ECG Finding, NCI Thesaurus)
An electrocardiographic finding in which the atrial rhythm is controlled by an electrical impulse from an artificial cardiac pacemaker.
(Paced Atrial Rhythm, NCI Thesaurus/CDISC)
A disorder characterized by an electrocardiographic finding of episodic atrial fibrillation with abrupt onset and termination.
(Paroxysmal Atrial Fibrillation, NCI Thesaurus)
A disorder characterized by a dysrhythmia with abrupt onset and sudden termination of atrial contractions with a rate of 150-250 beats per minute.
(Paroxysmal Atrial Tachycardia, NCI Thesaurus/CTCAE)
A disorder characterized by an electrocardiographic finding of episodic atrial tachycardia with abrupt onset and termination.
(Paroxysmal Atrial Tachycardia, NCI Thesaurus)
Electrocardiographic criteria used for the diagnosis of left atrial abnormality may include a bifid p wave, a biphasic p wave and/or a p wave duration of greater than 0.12 seconds.
