Key result
Interatrial block linked to atrial arrhythmias, stroke risk, cognitive impairment, and mortality.
Why the study?
Although initially considered benign, interatrial block subsets have been linked to atrial arrhythmias, stroke, cognitive impairment, and mortality, prompting investigation into early detection, imaging, risk factor modification, and stroke prevention.
Interatrial block, once considered benign, is associated with significant cardiovascular complications including atrial arrhythmias and stroke, warranting further investigation into early detection and management.
May warrant interatrial block evaluation in stroke risk assessment; leaves open targeted management pending prospective trials.
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 decreasing conduction in the region of Bachmann's bundle. Although initially considered benign in nature, specific subsets of IAB have been associated with atrial arrhythmias, elevated thromboembolic stroke risk, cognitive impairment, and mortality. As the pathophysiologic relationships between IAB and stroke are reinforced, investigation has now turned to the potential benefit of early detection, atrial imaging, cardiovascular risk factor modification, antiarrhythmic pharmacotherapy, and stroke prevention with oral anticoagulation. This review provides a contemporary overview of the epidemiology, pathophysiology, diagnosis, and management of IAB, with a focus on future directions.

Power et al. (2022) conducted a review in Interatrial block (IAB). Interatrial block (IAB) was evaluated. Interatrial block is associated with atrial arrhythmias, elevated thromboembolic stroke risk, cognitive impairment, and mortality, prompting investigation into early detection and management.
