Seventeen patients with non-cardiac chest pain were investigated by simultaneous ambulatory 24 hour ECG and oesophageal pH monitoring. While 11 patients lowered their oesophageal pH below 4 for a significant percentage, (3.4%) of recorded time and experienced chest pain, no simultaneous ECG changes occurred. In 10 patients chest pain was reproduced by an oesophageal acid perfusion test (Bernstein test). No changes in ECG record during the test were shown. We conclude that although reflux oesophageal pain may be difficult to differentiate from cardiac pain, clinically oesophageal pH changes do not produce any ECG changes.
对17例非心源性胸痛患者进行了24小时动态心电图和食管pH值同步监测。11例患者食管pH值降至4以下的时间占记录时间的显著比例(3.4%)并出现胸痛,但未同时出现心电图改变。10例患者经食管酸灌注试验(伯恩斯坦试验)诱发出胸痛,试验期间心电图记录无变化。我们得出结论,尽管反流性食管疼痛可能难以与心脏性疼痛相鉴别,但临床上食管pH值变化不会引起任何心电图改变。
