May support ECG localization of proximal LAD occlusion in anterior MI; hypothesis-generating and requires prospective validation.
Does ST segment deviation on admission ECG identify proximal versus distal left anterior descending artery occlusion in patients with acute anterior myocardial infarction?
ST segment depression >= 1 mm in all inferior leads on admission ECG is a useful and specific marker for identifying proximal LAD occlusion in patients with acute anterior myocardial infarction.
Tamura et al. (1995) studied this question.
