Abstract

A rare case of multiple infarction is described. An abnormal Q wave due to an old anteroseptal infarction was completely masked by a new contralateral posterior myocardial infarction. Coronary angiogram revealed multiple stenoses of segments 1 (100%), 7 (99%), 12 (90%) and 13 (99%). Left ventriculography also showed akinesis of segments 2, 3 4 and 6, and reduced wall motion in segments 1, 5 and 7. These findings, together with electrocardiographic changes from before the present attack reinforce the above interpretation.

摘要

本文描述了一例罕见的多发性梗死病例。既往前间隔梗死所致的异常Q波被新出现的对侧后壁心肌梗死完全掩盖。冠状动脉造影显示1段（100%）、7段（99%）、12段（90%）和13段（99%）多处狭窄。左心室造影还显示2段、3段、4段和6段运动减弱，1段、5段和7段室壁运动减弱。这些发现，连同本次发作前的心电图变化，进一步支持了上述解释。
