Objective To investigate the effect of ST depression in lead AVR on predicting the culprit artery in inferior ST- segment elevation myocardial infarction(STEMI).Methods One hundred and six patients with acute inferior STEMI underwent emergent coronary angiography were choosed,the relationship between electrocardiographic characteristics and angiographic findings was analyzed.ST depression in AVR was used for predicting the left circumflex artery (LCX) as the culprit to the population.Finally,the sensitivities and specificities of the ST depression in lead AVR for predicting the culprit artery were evaluated.Results The sensitivity and specificity of ST depression in lead AVR to predict LCX as the culprit were 53％ and 86％,respectively; 86％ and 55％ for predicting the right coronary artery (RCA) as the culprit.Conclusions ST depression in AVR is a simple method to predict the culprit artery in inferior STEMI.
