Key result
Interatrial block is a strong predictor of atrial fibrillation and stroke across multiple clinical scenarios, highlighting the need for randomized trials to evaluate early anticoagulation.
This review highlights the association between interatrial block and atrial fibrillation (Bayés Syndrome) and emphasizes the utility of the 12-lead ECG in predicting atrial fibrillation.
Supports incorporating interatrial block into AF risk assessment; extends evidence but leaves open anticoagulation benefits pending RCTs.
In the past few decades, extensive research has been conducted on atrial conduction disorders and their clinical relevance. An association between interatrial block (IAB) and supraventricular arrhythmias [most commonly atrial fibrillation (AF)] has been discovered and extensively investigated. We coined the term "Bayés Syndrome" to describe this association, and the medical community has accepted the eponym in recognition to the scientist who discovered most of the aspects associated with it. In this non-systematic review, we will focus on the association between IAB and AF, with special emphasis on the value of the surface 12-lead ECG as a valid tool to predict AF.

Adrián Baranchuk (2017) conducted a review in Bayes' Syndrome (Interatrial block and atrial fibrillation). Interatrial block vs. Absence of interatrial block was evaluated. Interatrial block is a strong predictor of atrial fibrillation and stroke across multiple clinical scenarios, highlighting the need for randomized trials to evaluate early anticoagulation.
