Background Atrial fibrillation is the most frequent sustained arrhythmia. Atrial fibrillation often
recurs after restoration of normal sinus rhythm. Antiarrhythmic drugs have been widely used …

Interatrial block (IAB) is an electrocardiographic pattern describing the conduction delay
between the right and left atria. IAB is classified into 3 degrees of block that correspond to …

Although advanced interatrial block (aIAB) is an established electrocardiographic
phenotype, its prevalence, incidence, and prognostic significance in the general population …

Background and objectives Inter-atrial block (IAB) is characterized by a delay of inter-atrial
conduction and is defined electrocardiographically by a P-wave duration (PWD)> 120 ms …

Background Data are lacking on the characteristics of atrial activity in centenarians,
including interatrial block (IAB). Objective The aim of this study was to describe the …

Bayés syndrome is a new clinical entity, characterized by the association of advanced
interatrial block (IAB) on surface electrocardiogram with atrial fibrillation (AF) and other atrial …

Background Advanced interatrial block (aIAB) on the surface electrocardiogram (ECG),
defined as a P‐wave duration≥ 120 milliseconds with biphasic (±) morphology in inferior …

Interatrial block (IAB) represents delay or block of conduction between the atria. IAB has
been shown to predict the development or recurrence of atrial fibrillation (AF) in various …

Electrocardiograms (ECGs) have been employed to medically evaluate participants in
population-based studies, and ECG-derived predictors have been reported for incident atrial …

The past few years have given rise to extensive research on atrial conduction disorders and
their clinical relevance. Most notably, an association between interatrial block and …
