Po-05-141 association of interatrial block and the development of atrial fibrillation among patients with hypertrophic cardiomyopathy

Atrial fibrillation (AF) is the most common sustained arrhythmia among those with hypertrophic cardiomyopathy (HCM), affecting 1 in 5 patients. The combination of HCM and AF is associated with an increased risk of stroke, heart failure, and mortality. Interatrial block (IAB) is a distinct electrocardiographic (ECG) pattern describing conduction delay between the right and left atria through Bachmann ’s bundle. IAB has been identified as a predictor of AF across several disease states including congestive heart failure, valvular disease, and cardiac amyloidosis.
