Anterior wall myocardial infarction
The convex upwards ST elevation which is classical of acute myocardial infarction was described by Pardee in 1920 and has been called the “Pardee’s sign” [Pardee HEB. An electrocardiographic sign of coronary artery obstruction. Arch Intern Med 1920; 26: 244– 257]. The current ECG show QS complexes in V1 and V2 and poor R waves in V3 and V4. ST segment elevation is maximum in lead V2. T waves are inverted in leads I, aVl and V1 to V5.
