Definitions related to atrioventricular block:
-
Delayed or lack of conduction of atrial depolarizations through the atrioventricular node to the ventricles.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Impaired impulse conduction from HEART ATRIA to HEART VENTRICLES. AV block can mean delayed or completely blocked impulse conduction.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(atrioventricular block by ecg finding) An electrocardiographic finding of delayed or blocked cardiac electrical impulse conduction from the atria to the ventricles at the level of the atrioventricular node.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Atrioventricular (AV) block is partial or complete interruption of impulse transmission from the atria to the ventricles. The most common cause is idiopathic fibrosis and sclerosis of the conduction system. Diagnosis is by electrocardiography; symptoms and treatment depend on degree of block, but treatment, when necessary, usually...Merck & Co., Inc., 2020

Atrioventricular (AV) block occurs when atrial depolarizations fail to reach the ventricles or when atrial depolarization is conducted with a delay. Three degrees of AV block are recognized.WebMD, 2019
-
Atrioventricular (AV) block is a cardiac electrical disorder defined as impaired (delayed or absent) conduction from the atria to the ventricles. The severity of the conduction abnormality is described in degrees: first-degree; second-degree, type I (Wenckebach or Mobitz I) or type II (Mobitz II); and third-degree (complete) AV block....Athenahealth, Inc., 2019
