Smith and Meyers answer: First , LM occlusion is uncommon in the ED because most of these die before they can get a 12-lead recorded. She had a proven 100% Left Main occlusion No ST shift in aVR This pattern of RBBB/LAFB was also the most common pattern in Fiol et al. Widimsky P et al. Knotts et al. References 7.

A formal echocardiogram was completed the next day and again showed a normal ejection fraction without any focal wall motion abnormalities to suggest CAD. In the largest study looking at this topic by Mizusawa et al., She has not had a heart catheterization or after this event so the presence or absence of CAD is still unknown.

See this paper by Widimsky et al, which shows the high association of RBBB, especially with LAFB, with LAD occlusion. This is a very common misread.

His ED cardiac ultrasound (which is not at all ideal for detecting wall motion abnormalities, and is also very operator dependent for this finding) was significant for depressed global EF. In this study of dialysis patients with severe CAD, 77% had an abnormal resting EKG and the most common abnormality was LVH. Herzog et al.
