对未累及心脏的炎症性肠病患者急诊心电图QT间期的研究

Study of QT interval in the emergency ECG of patients with inflammatory bowel disease not involving in heart

目的探讨未累及心脏的炎症性肠病患者急诊心电图QT间期变化。方法实验组选取2013年5月~2015年5月在我院急诊科就诊的炎症性肠病患者60例,无心脏病史及电解质失衡;对照组为54例健康志愿者。两组均常规行12导联心电图,记录QT间期变化。结果实验组红细胞沉降率和C反应蛋白水平均高于对照组,差异有统计学意义（P〈0.05）,实验组心率校正QT间期及其离散度均显著大于对照组,差异有统计学意义（P〈0.05）;实验组和对照组心电回波资料比较差异无统计学意义（P〉0.05）。结论炎症性肠病患者常伴有QT间期延长,此类患者应常规行12导联心电图检查,预防因长QT间期诱发的恶性心律失常,改善患者预后。

Objective To explore the changes of QT interval in the emergency ECG of patients with inflammatory bowel disease not involving in heart. Methods 60 patients with inflammatory bowel disease who were admitted to our hospital in emergency Department from May 2013 to May 2015 were selected in the experiment group, and they were free from history of heart disease and electrolyte imbalance; 54 healthy volunteers were selected in the control group.The two groups were given 12-lead ECG routinely, and changes of QT interval were recorded. Results Erythrocyte sedimentation and C-reaction protein levels in the experiment group were both higher than those in the control group（P〈0.05）, and heart rate-corrected QT interval and distribution value in the experiment group were both higher than those in the control group（P〈0.05）; the ECG echo data in the two groups were not statistically different（P〉0.05）. Conclusion The patients with inflammatory bowel disease are usually accompanied with QT interval prolonging. Such patients should be given 12-lead ECG exam routinely, so as to prevent malignant arrhythmia induced by long QT interval, and improve patients＇ prognosis.
