6 Observe furthermore edit References edit Reciprocal ST depression in I, aVL suggests a possibility of RCA lesion.In a cardiac stress test, an ST depressive disorders of at least 1 mm after adenosine management signifies a reversible ischaemia, while an workout stress check needs an ST depressive disorders of at least 2 mm to significantly indicate reversible ischaemia. Patients of acute IWMI with ST depression in apicolateral leads have more occurrence of multivessel disease with significant LV dysfunction. AWMI patients without reciprocal changes in inferior leads have a better LVEF. Patients of acute AWMI with Q waves in inferior leads indicate a smaller infarct with higher incidence of mid/distal LAD occlusion and a relatively preserved LV function. Also, patients with ST depression in I, aVL showed higher incidence of right coronary artery (RCA) lesion (23/27) (P < 0.001).

VI-V3 leads and 15% (3/20) patients without significant reciprocal changes in anterior and lateral leads had LVEF < 40%. 12.5% (4/32) patients with reciprocal changes in anterior i.e. The echocardiogrpahy of these 19 patients showed that 15/19 (78.94%) of these had LV ejection fraction (EF) > 40% as against only 4/19 (21.05%) patients with LVEF or = ST elevation in inferior leads were found to have more occurrence of multivessel disease (21/27) with LVEF < 40% (50/64 i.e. In presence of SVD, 80% (8/10) patients were found to have a distal/mid LAD occlusion. CAG revealed 10/19 and 9/19 patients to have single vessel disease (SVD) and multivessel disease (MVD), respectively. Nineteen patients underwent (CAG) and all 70 patients underwent 2D echocardiography. In patients with acute anterior wall MI (AWMI), Q wave in inferior leads was found in 38.8% (70/180) patients. 285/300 (95%) patients underwent echocardiography and 62/300 (20.67%) underwent coronary angiography (CAG). Three hundred patients of acute myocardial infarction (AMI) (180 anterior, 120 inferior) aged between 30-90 years (mean age - 60 yrs M:F - 220:80) were studied with regard to the reciprocal lead changes which were correlated with the culprit coronary artery and LV function. To study the relevance of the ECG changes in the reciprocal leads in patients with acute anterior and inferior wall myocardial infarction, with regard to culprit artery localization and left ventricular (LV) function.
