目的:探讨化疗药物对心电图QRS波群电压的影响。方法:回顾性分析100例恶性肿瘤患者在化疗期间出现QRS波群电压降低的临床资料。结果:100例恶性肿瘤患者化疗期间出现肢导联低电压33例(33%),其中左胸导联低电压27例(27%),右胸导联低电压3例(3%),肢导联和左胸导联低电压26例(26%);全导联低电压11例(11%)。结论:恶性肿瘤患者化疗期间可出现QRS波群电压降低,可能为药物引起的心肌损伤表现,化疗时应给予关注及预防。
Objective: To investigate the effect of chemotherapeutic drugs on QRS complex voltage of ECG. Methods: A retrospective analysis of 100 cases of malignant tumor patients during chemotherapy, QRS wave group decreased voltage clinical data. RESULTS: Thirty patients (33%) had lower extremity leads during chemotherapy, including 27 cases of left chest leads (27%), 3 cases of right chest leads (3%), Lead and left chest lead low voltage in 26 cases (26%); all lead low voltage in 11 cases (11%). Conclusions: The voltage of QRS complex may decrease during chemotherapy in patients with malignant tumor, which may be caused by drug-induced myocardial injury. Chemotherapy should be given attention and prevention.
