Interatrial Block

MedGen UID:

•
Disease or Syndrome
Synonyms: Block, Interatrial; Conduction Delay, Interatrial; Interatrial Blocks; Interatrial Conduction Delay; Interatrial Conduction Delays

Definition

Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann''s bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome. [from MeSH]
