Thirty patients with suspected esophageal originated chest pain were studied by 24 h esophageal pH monitoring. All of them complained of chest pain, heart burn, acid reflux or dysphagia. The result showed abnormal pH in 26 patients (86.7%). Sixteen of them had pH abnormalities in both day and night, whereas 8 had only abnormal day pH, and 2 pH out of the normal limits at night. Chest pain episode was correlated with the abnormalities in 18 cases (60%). Four patients with coronary heart disease showed simultaneous gastro-esophageal reflux originated chest pain; the positive correlation was obtained. Their diagnosis of cardiac chest pain was doubtful. We suggested that 24h pH monitoring was a significant method to determine the cause of chest pain.
对30例疑似食管源性胸痛患者进行了24小时食管pH监测。所有患者均主诉胸痛、烧心、反酸或吞咽困难。结果显示26例患者（86.7%）pH异常。其中16例昼夜pH均异常，8例仅日间pH异常，2例夜间pH超出正常范围。18例（60%）胸痛发作与pH异常相关。4例冠心病患者同时存在胃食管反流源性胸痛，呈正相关。其心源性胸痛的诊断存疑。我们认为24小时pH监测是确定胸痛病因的重要方法。
