Interatrial block as a predictor of embolic stroke
The American Journal of Cardiology, 2005Interatrial 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

Interatrial block (IAB; P wave > or =110 ms) is a potent correlate of left atrial (LA) enlargement and electromechanical dysfunction and a strong predictor of atrial tachyarrhythmias, in particular, atrial fibrillation. Although these associations increase its risk for embolism, i.e., cardioembolic stroke, such a phenomenon has been inadequately ...

Second-degree interatrial block: A case series
Journal of Electrocardiology, 2019Advanced interatrial block (IAB) (P-wave ≥120 ms and biphasic P-wave in leads II, III and aVF) is a prevalent ECG pattern frequently associated with supraventricular arrhythmias and stroke, especially in patients with structural heart disease.

Prevalence of interatrial block in a general hospital population
The American Journal of Cardiology, 2003The present investigation showed a very high prevalence of IAB in a hospital population. Above the age of 60 years, more patients in sinus rhythm had IAB than those without it. Considering the consequences of atrial fibrillation, including subsequent stroke in such patients, it is essential that IAB be recognized early because it is associated with a ...

Interatrial Block: The Pandemic Remains Poorly Perceived
Pacing and Clinical Electrophysiology, 2009Interatrial block (IAB; P duration ≥110 ms) is a common electrocardiogram abnormality, which in addition to reduced left atrial function predicts atrial fibrillation and other arrhythmias. P terminal force (Ptf) ± biphasic P in lead V1≥ the area of one small square on the grid also indicates left atrial abnormality, particularly left atrial ...

A case of interatrial block is reported, involving the upper part of left atrium, demonstrated by oesophageal recordings at different levels. Abnormally retrograde atrial depolarisation in the upper part of the left atrium was observed, but normal descending depolarisation in the lower part of the left atrium suggested that interatrial conduction was ...
