结果介入组动态心电图示心肌缺血总负荷较溶栓组明显降低（P<0.01）；
Results Compare to the intravenous thrombolytic therapy group , Dynamic electrocardiogram demonstrated that total ischemia burden in PCI group were decreased significantly (P<0.01).
该技术较心电图运动负荷试验有更高的敏感性和特异性，并且没有辐射，根据需要还可以重复多次试验。
The advantages of the technique include higher sensitivity and specificity compared to EKG stress testing and lack of irradiation, allowing the possibility for repeated testing as needed.
