对20例非心源性胸痛病人进行了食管研究以评价短期或长期测压及pH监测的诊断价值.使用两种激发试验对病人进行基本食管测压,即:Bernstein试验和腾喜龙(edrophoniun)静脉注射试验.对病人分别记录了24小时动态食管pH及运动功能.Betnstein试验中有2例产生了胸痛,而腾 Esophageal studies were performed on 20 patients with non-cardiac chest pain to evaluate the diagnostic value of short-term or long-term manometry and pH monitoring. Two types of challenge tests were performed on patients with basic esophageal manometry: Bernstein’s test and edrophoniun ) Intravenous injection test, the patient recorded 24-hour dynamic esophageal pH and motor function.Betnstein test in 2 cases of chest pain,
