摘要
Seventy-eight patients underwent coronary angiography and submaximal tre-admill exercise test to evaluate the Q-Tc,Q-Tr and ΔQ-Tc criteria for predicting co-ronary artery disease(CAD).The sensitivity,specificity,predicting value and correctdiagnostic rate of the Q-Tc and Q-Tr criteria were 84,76,83,81 percent and 69,88,89,77 percent,respectively,which had no significant differences when compared with ST de-pression.The Q-Tc had higher specificity(94%)than that of ST depression but less sen-sitivity(58%).These criteria could reflect the severity of coronary artery disease identi-fied with coronary angiography.Therefore,these criteria are usefel to interpret the resultsof stress test.
