Left Bundle Branch Block Does Not Mean Left Coronary Artery Block

Left bundle branch block (LBBB) can be caused by special patterns of coronary disease such as distal LAD occlusion combined with right coronary artery (RCA) obstruction, or transient bradycardia-related LBBB due to increased parasympathetic tone with RCA occlusion. [...]in the case of calcific aorti...

Description
Summary:Left bundle branch block (LBBB) can be caused by special patterns of coronary disease such as distal LAD occlusion combined with right coronary artery (RCA) obstruction, or transient bradycardia-related LBBB due to increased parasympathetic tone with RCA occlusion. [...]in the case of calcific aortic stenosis, there is both impingement of calcium upon the proximal LB as well as hypertrophy and more often there is not LAD occlusion.
