They usually are normal variants and rarely require further evaluation. The condition is more common in women than in men. The pathophysiologic mechansim most consistent with this is that a chronic hemodynamic burden initially produces left atrial enlargement which in turn predisposes to atrial fibrillation. Thus, left bundle branch block causes a loss of normal coordination between the two ventricles, which decreases the efficiency of the heartbeat. However, it is more common for left atrial enlargement to occur than it is for the right atrium to enlarge. 3%) had LA < 4 cm.
