Right bundle-branch block in anterior acute myocardial infarction in the coronary intervention era: Acute angiographic findings and prognosis

Spontaneous recovery of complete atrioventricular block complicating acute anterior wall ST elevation myocardial infarction

“…The reduced incidence in non-thrombolysed patients reflects the overall improvement in medical management 8–10. Even though the incidence has been found to be decreased, right bundle branch block is still found to be associated with poor clinical outcome in patients with anterior myocardiaI infarction even in the coronary intervention era 11. The patient described here belonged to the high-risk category, and primary PCI would have been a better choice for him.…”

Significance of an isolated new right bundle branch block in a patient with chest pain

“…In a recent retrospective study, nearly 50% of 427 AMIs with RBBB had no ST elevation,3 despite the fact that the infarct-related artery was more frequently completely occluded at the time of coronary angiography 37 The LAD artery is most commonly involved,7 8 and left main stem occlusion may present in 26–37% with RBBB without ST elevation 3 9. Septal perforator arteries of the LAD perfuse the right bundle branch and the anterior fascicle of the left bundle branch in 90%, and their occlusion leads to a RBBB.…”

Changing axis deviation and intermittent right bundle branch block during acute myocardial infarction

“…[1] The prognosis of right bundle branch block in the absence of underlying cardiac disease is good but it may be poor in other cases, particularly coronary artery disease [2,3]. Changing bundle branch block [4,5], new right bundle branch block [6], right bundle branch conduction disturbances [7] have been reported in literature.…”
