Why the study?
Does a greater degree of ST-segment depression in lead III than ST-segment elevation in lead aVL predict proximal LAD occlusion in patients with anterior AMI?
Does a greater degree of ST-segment depression in lead III than ST-segment elevation in lead aVL predict proximal LAD occlusion in patients with anterior AMI?
In patients with anterior AMI, comparing ST-segment depression in lead III to ST-segment elevation in lead aVL provides a highly specific and sensitive ECG criterion for identifying proximal LAD occlusion.
