Association between interatrial block, left atrial fibrosis, and mechanical dyssynchrony: Electrocardiography ‐magnetic resonance imaging correlation

ConclusionAdvanced IAB is associated with larger LA volumes, lower emptying fraction, and more fibrosis. Longer P ‐wave duration is also associated with more LA fibrosis and higher LA mechanical dyssynchrony.
