对４２例冠心病（ＣＡＤ）患者和１５例正常人进行食道心房调搏（ＴＡＰ）心电图负荷试验，同时进行ＴＡＰ－９９ｍＴｃ－ＭＩＢＩ（α－甲氧基异丁基异睛）心肌灌注断层显像，并将两种方法进行配对比较。结果表明：ＴＡＰ心电图对ＣＡＤ诊断的灵敏度为４５．２４％，特异性为１００％，ＴＡＰ，心肌断层显像的灵敏度为８５．７１％，特异性为９３．３３％。对冠心病的检出率ＴＡＰ心肌断层显像显著高于ＴＡＰ心电图（Ｐ＜０．００５）。提示：ＴＡＰ负荷试验结合心肌断层显像可以大大提高诊断ＣＡＤ的灵敏度，对那些不能耐受运动试验的早期ＣＡＤ和可疑ＣＡＤ的患者尤为适用。
Twenty-four patients with coronary artery disease (CAD) and 15 normal subjects underwent esophageal atrial pacing (TAP) electrocardiographic stress test and TAP-99mTc-MIBI myocardial perfusion tomography Compare the two methods. The results showed that the sensitivity of TAP electrocardiogram in diagnosis of CAD was 45.24% and the specificity was 100%. The sensitivity and the specificity of TAP and myocardial imaging were 85.71% and 93.33% respectively. The detection rate of coronary heart disease TAP myocardial imaging was significantly higher than the TAP ECG (P <0.005). Tip: TAP stress tests combined with myocardial imaging can greatly improve the diagnostic sensitivity of CAD, especially for patients with early CAD and suspect CAD who can not tolerate exercise testing.
