ABNORMAL VENTRICULAR REPOLARIZATION IN ASSOCIATION WITH MYOCARDIAL BRIDGING

Myocardial bridging causing compression of epicardial arteries may be an incidental finding at coronary arteriography. Bridging rarely cause s myocardial ischaemia. A young man presented with chest pain and stri king abnormalities of ventricular repolarisation that initially were t reated as myocardial infarction. At cardiac catheterisation the corona ry arteries were normal apart from the presence of a myocardial bridge affecting a major diagonal branch of the left anterior descending art ery. Echocardiography was normal with no features of hypertrophic card iomyopathy.
