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.
