Right Bundle-Branch Block Associated with Transient Left Posterior Hemiblock in a Case of Acute Myocardial Infarction
Abstract
The intraventricular conduction defect of left posterior hemiblock is very uncommon. Its occurrence as a transient phenomenon during the course of acute myocardial infarction, as described in this report, is exceptionally rare. The presentation revealed a planar reorientation of QRS forces, and demonstrated the masking effect of left posterior hemiblock on the parameters .of anterolateral myocardial ischaemia.
