22例冠心病及13例非冠心病者大剂量潘生丁(0.75mg/kg)试验与冠脉造影、心肌活检对照,探讨心电图多参数指标对冠心病诊断的意义。ΔST 敏感性为68%,特异性为92%。ΔST、ΔQ、ΔR 与ΔRST 多参数综合指标敏感性为77.3%,特异性为76.9%。研究结果表明,以 ST 段变化参数最优,其它参数可作参考,而平均电轴偏移与ΔQ-Tc 无诊断意义。提示大剂量潘生丁心电图试验是目前诊断冠心病较简便、安全、可靠、易推广的辅助检查方法。
22 cases of coronary heart disease and 13 cases of non-coronary heart disease, high-dose dipyridamole (0.75mg / kg) test and coronary angiography, myocardial biopsy control to explore the significance of multi-parameter ECG in the diagnosis of coronary heart disease. The ΔST sensitivity was 68% and the specificity was 92%. The multi-parameter comprehensive indexes of ΔST, ΔQ, ΔR and ΔRST have a sensitivity of 77.3% and a specificity of 76.9%. The results show that the best parameters of ST segment changes, other parameters can be used as a reference, and the average axial deviation and ΔQ-Tc no diagnostic significance. Tip high-dose dipyridamole ECG test is the diagnosis of coronary heart disease is relatively simple, safe, reliable and easy to promote the auxiliary examination.
