Abstract：Objective Combining results of coronary angiography, to analyse the predictive values of limb lead ST segment changes for identifying the coronary occlusion sites in patients with acute anterior wall myocardial infarction.MethodsEighty-four patients who had undergone coronary angiography inspections for acute anterior wall myocardial infarction were selected as candidates and their ST segment changes in limb leads of ECG after onset were analysed. ResultsAccording to the results of coronary angiography, at the lesion of the proximal end of anterior descending branch(with or without distal occlusion), ST segment changes in limb leads Ⅱ, Ⅲ, and aVF were mostly expressed as depression≥0.1 mV while elevation or unobvious depression of ST segment in limb leads Ⅱ, Ⅲ, and aVF mostly occurred at the lesion of the distal end of anterior descending branch(without proximal occlusion). ConclusionBy analysing the ST segment changes in limb leads of ECG, coronary occlusion sites can be predicted, which serves as an references for early diagnosis and treatment options for patients with acute anterior wall myocardial infarction.
