乳腺癌术后患者给予化疗和放射治疗后的心电图变化

目的 探讨乳腺癌患者术后给予化疗和放射治疗后心电图的变化. 方法 对58例乳腺癌患者采用了手术治疗,术后对观察组（29例）患者给予化疗和放射治疗,并与单独进行化疗的对照组（29例）进行了心电图变化的比较. 结果 观察组患者中有11例发生心电图异常（37.93%）,对照组有2例出现心电图异常（9.52%）（χ^2=8.03,P＜0.05）.观察组中左侧乳腺癌患者发生异常心电图的比例（7/15）略高于右侧（4/14）（χ^2=1.01,P＞0.05）. 结论 化疗联合放射治疗乳腺癌术后患者,可明显增加心脏毒性.

Study on the change of ECG after chemotherapy and radiotherapy in treatment of patients with breast cancer

Objective To explore the change of ECG after chemotherapy and radiotherapy in treatment of patients with breast cancer. Methods 58 patients with breast cancer were treated with surgery,after operation the observation group were treated with chemotherapy and radiotherapy,and the control group was given chemotherapy singly.The change of ECG was compared between two groups. Results In the observation group,11 patients had abnormal ECG(37.93%),In the control group,2 patients had abnormal ECG(9.52%)(x2=8.03,P ＜0.05＝.In addition,in the observation group the incidence of abnormal ECG in the patients with left breast cancer(7/15)was slightly higher than that with right breast cancer(4/14)(x2=1.01,P ＞ 0.05). Conclusion The treatment of chemotherapy combined with radiation could significantly increase cardiac toxicity in the patients with breast cancer.
