2017, Journal of ElectrocardiologyCitation Excerpt :Some suggested this discrepancy was due to myocardial stunning [547]; whereas, others suggested that the inconsistency of the predictive value of the QRS score were due to its wide confidence intervals [174]. Additionally, the QRS score appears to perform better in anterior MI compared with inferior (though this problem was more significant in other ECG based infarction scores) [207] which may add to the heterogeneity in its performance [96,102,149,543,548,549]. However, a study of anterior MIs receiving timely reperfusion found that the QRS score did not correlate with the severity of myocardial dysfunction by echocardiography [254].
