Progression of partial to advanced interatrial block

Journal of Electrocardiology, 2006
Interatrial block (IAB), prolonged conduction between the atria, is denoted by P waves of 110 milliseconds or more and may manifest as partial or advanced. Theoretically, partial IAB may progress to its advanced counterpart if conduction delay increases to complete block.

Advanced Interatrial block induced by flecainide

Journal of Electrocardiology
We present a case of advanced interatrial block induced by flecainide toxicity. We discuss the implications of this conduction abnormality.

Atypical advanced interatrial block due to giant atrial lipoma

PACE - Pacing and Clinical Electrophysiology, 2021
In 2012, a consensus report on interatrial blocks (IAB) was published, which established the electrocardiographic criteria for advanced IAB (A-IAB), consisting of a P-wave duration ≥120 ms plus biphasic ± morphology in the inferior leads (II, III, and ...

Interatrial conduction block with retrograde activation of the left atrium and paroxysmal supraventricular tachyarrhythmias: influence of preventive antiarrhythmic treatment [PDF]

International Journal of Cardiology, 1989
Patients with advanced interatrial conduction block with retrograde activation to the left atrium present a high incidence of supraventricular tachyarrhythmias.

Reevaluation of the Criterion for Interatrial Block

The American Journal of Cardiology, 2006
The importance of the interatrial block has often been overshadowed by the debate on the appropriate cutoff to define its excessively wide P waves. However, by far, most publications have accepted P waves of >or=110 ms to represent abnormal interatrial conduction on the electrocardiogram.

Advanced Interatrial Block: A Classic Electrocardiogram

Cardiology, 2005
Interatrial block (IAB; P wave ≧110 ms) indicates conduction delay between the right and left atria. IAB can present as partial or advanced and is denoted on the electrocardiogram (ECG) by bifid or biphasic P waves, respectively, the latter in inferior leads.

Interatrial blocks: Diagnosis and clinical significance

Medicina Clínica (English Edition), 2020
In 1979 Bayés de Luna described interatrial blocks (IAB). Following the same principle of classification of blocks in other structures of the heart, he divided them into first (partial IAB), second (atrial aberrancy) and third degree (advanced IAB). Atypical forms of these blocks were recently described.

Interatrial and sinoatrial block, with an illustrative case

American Heart Journal, 1946
Abstract Sinoatrial block of two types has been described; (1) with progressive prolongation of sinoatrial conduction time leading to a dropped beat; and (2) dropped beats without such preceding conduction changes. These are strictly analogous to the Wenckebach and the Mobitz types of atrioventricular block.

Interatrial block as a predictor of embolic stroke

The American Journal of Cardiology, 2005
Interatrial block (IAB), defined as a prolonged (>/=110 ms) P wave, is remarkably prevalent in general hospital populations and is associated with an enlarged, poorly contractile left atrium. The investigators sought to determine whether there is an increased incidence of IAB in patients with embolic strokes. Patients' medical records were reviewed for
