Abstract In this paper, three patients were selected whose inferior wall lead Ⅱ, Ⅲ and aVF had QS, rS and qrS type morphology, respectively in routine electrocardiogram (ECG). Through crosscheck analysis by ECG and vectorcardiogram(VCG), the three cases were specifically diagnosed with inferior wall myocardial infarction, left anterior fascicular block and inferior wall myocardial infarction complicating left anterior fascicular block. It indicates that VCG is clinically valuable in the differential diagnosis of inferior wall myocardial infarction and left anterior fascicular block.
