目的 探讨癌症患者心电图改变与预后之间的关系。方法 对132例临床死亡的肺癌(77)、胃癌(30)、食道癌(16)及其它癌症(9)患者临终前半年内的心电图各取3份,在心率、低电压、心律失常、ST-T改变、QT、QTc延长及QTd、QTcd等方面对不同性别、年龄、病理诊断、存活时间、治疗方法的病例进行比较分析。结果3次心电图中,心率、ST-T改变呈递增趋势。肺癌及1年内死亡的增加最明显。QTd的范围是15～110ms;QTcd的范围是16～130ms。临终前2W内心电图以采用手术+放疗+化疗治疗的改变最多。结论 心电图改变与预后呈正相关。心率增快、ST-T改变、QTcd可作预测的参考指标。
Objective To explore the relationship between electrocardiographic changes and prognosis in cancer patients. Methods Three of the electrocardiograms in the first half of the first half of the end of the clinical deaths of lung cancer (77), gastric cancer (30), esophageal cancer (16) and other cancers (9) of 132 patients died at heart rate, low voltage, arrhythmia, ST- The changes in T, QT, QTc, and QTd, QTcd, etc. were compared among different sex, age, pathological diagnosis, survival time, and treatment methods. Results In the 3 ECGs, the changes of heart rate and ST-T showed an increasing trend. The increase in lung cancer and death within 1 year is most pronounced. The QTd range is 15 to 110 ms; the QTcd range is 16 to 130 ms. Before the death of 2W electrocardiogram with surgery + radiotherapy + chemotherapy treatment changes the most. Conclusion Electrocardiographic changes are positively correlated with prognosis. Faster heart rate, ST-T changes, and QTcd can be used as a reference for prediction.
