Are there differences among patients with inferior acute myocardial infarction with ST depression in leads V2 and V3 and positive versus negative T waves in these leads on admission?

We assessed whether there are differences among patients with inferior acut e myocardial infarction and ST segment depression in leads V2-V3 between th ose with positive versus negative T waves on admission. We found no differe nces in the prevalence of concomitant significant left anterior descending coronary artery stenosis and anterior or posterior wall motion abnormalitie s on echocardiography between the two groups. Precordial ST segment depress ion with negative T wave may be the early electrocardiographic pattern of p osterior infarction, reflecting ST segment elevation with positive T waves that would have been detected by leads facing the posterior wall.
