[Relationship between electrocardiographic pattern and angiographic findings in inferior myocardial infarction].
The relationship between electrocardiographic pattern and angiographic features was assessed in 86 patients with inferior myocardial infarction. Although the occurrence of inferior Q wave was similar in patients with isolated left circumflex (LCX) or right coronary artery (RCA) occlusion, lateral Q wave and abnormal R wave in lead V1 were more frequent in the former. In patients with LCX-related infarction, abnormal R wave in lead V1 associated with inferior and/or lateral Q waves may indicate left ventricular dysfunction, total occlusion of the LCX without collateral circulation, and high cardiac event rate during longterm follow-up.
