- W2389353731 abstract "Objective:To study the diagnosis value of the changes of Q -Tc, Q -Tr and Q -Tcd during treadmill exercise test for coronary heart disease (CHD). Methods; Choose 98 CHD patients and 51 normal persons who have been performed coronary angiography for study the changes of Q -Tc, Q -Tr and Q -Tcd in 12 leads ECG during and after exercise,those paramters were compared between CHD group and normal group. Results:The sensitivity, specificity, predicting value and correct diagnostic rate of the Q -Tc and Q -Tr were 84% , 76% , 83% , 81% and 69% , 88%, 89%, 77% respectively, which were no significant differences compared with ST depression. The Q-Tcd had higher specificity (94%), and less sensitivity (58%) than above parameters. Conclusion:The changes of Q-Tc, Q-Tr and Q -Tcd and ST depression in the exercise test are practical value for coronary heart disease." @default.
