评价老年食管癌和贲门癌合并心电图异常对外科手术的影响。方法：作者经手术治疗65岁以上老年食管癌和贲门癌共138例，其中术前合并心电图异常者83例，占60．1％（83／138）；术前除左束支传导阻滞、广泛性心肌供血不足、陈旧性及亚急性心肌梗塞患者给予7－10天心脏保护性药物治疗外，余均未作任何特殊性治疗。结果：术后共发生井发症9例次，占10．8％（9／83），其中心跳骤停1例次，急性心肌梗塞1例次，重度房颤2例次，胸胃局灶性坏死穿孔5例次，均经抢救性（和／或手术）治疗痊愈，本组无死亡者。结论：老年食管癌和贲门癌患者合并心电图异常，并不一定是心功能异常，并不一定影响外科手术治疗。
To evaluate the effect of electrocardiogram abnormalities in elder patients with esophageal and cardiac cancers on surgical operations. METHODS: The authors treated 138 cases of esophageal and cardia cancers older than 65 years of age, including 83 cases with abnormal electrocardiogram preoperatively, accounting for 60.1% (83/138) of the patients; preoperatively, left bundle branch block, Extensive myocardial insufficiency, old and subacute myocardial infarction patients were given 7-10 days of cardioprotective drug therapy, but none of them had any special treatment. Results: Postoperative cavitation occurred in 9 cases, accounting for 10.8% (9/83). There were 1 case of central arrest, 1 case of acute myocardial infarction, 2 cases of severe atrial fibrillation, and thoracic and gastric lesions. Five cases of perforation of sex necrosis were cured by salvage (and/or surgery). No deaths occurred in this group. Conclusion: The abnormal electrocardiogram in patients with esophageal and cardiac cancer in the elderly is not necessarily an abnormal cardiac function and does not necessarily affect surgical treatment.
