| 摘 要： | 目的 :探讨阵发性室上性心动过速 (PSVT)时 ST段压低对冠心病 (CAD)的诊断价值。方法 :将 40例年龄 >45岁无 CAD临床证据的 PSVT患者分为两组 :A组在 PSVT时伴 ST段压低 ,B组无压低。两组患者均行运动试验和冠状动脉造影。结果 :A组 2 0例中 8例 (40 % )有 CAD;B组 2 0例中无一例有 CAD(P <0 .0 5)。结论 :在 >45岁 PSVT患者中 ,CAD和心肌缺血是导致伴 ST段压低的原因之一。即使无 CAD的临床表现 ,此类患者亦应考虑行运动试验或冠状动脉造影 ,以便早期发现和治疗并存的 CAD。

| Abstract: | Objective:To explore the significance of STsegment depression during paroxysmal supraventricular tachycardia (PSVT) in the diagnosis of coronary heart disease (CAD).Method:40 patients aged >45 years with PSVT without clinical evidence of CAD were divided into 2 groups:Group A included 20 cases with STsegment depression during PSVT.Group B consisted of 20 cases without STsegment during PSVT.They all underwent both treadmill exercise testing and coronary angiography.Result:8(40%) of 20 cases in Group A had CAD,while none in Group B (P< 0.05 ).Conclusion:The data suggest that CAD and myocardial ischemia is one,but not the only of the mechanisms involved in the genesis of STsegment depression during PSVT in patients >45 years old. |
