Key result
QRS score correlated significantly with myocardial SPECT and coronary angiography results, surpassing cumulative ST depression in sensitivity and specificity for detecting ischemic heart disease.
Why the study?
Does the QRS score improve the diagnostic accuracy of exercise stress testing for detecting ischemic heart disease compared to ST-segment displacement?
Observational (n=212)
Does the QRS score improve the diagnostic accuracy of exercise stress testing for detecting ischemic heart disease compared to ST-segment displacement?
The QRS score during exercise testing provides superior diagnostic accuracy for ischemic heart disease compared to traditional ST-segment depression, particularly in men.

QRS score may aid ECG detection of ischemic heart disease; hypothesis-generating and requires prospective validation before clinical adoption.
Tóth et al. (2001) conducted an observational in Ischemic heart disease (n=212). QRS score vs. Cumulative ST depression was evaluated on Correlation to the findings of the stress myocardial perfusion SPECT or coronary angiography. QRS score correlated significantly with myocardial SPECT and coronary angiography results, surpassing cumulative ST depression in sensitivity and specificity for detecting ischemic heart disease.
