目的 :探讨食管癌伴阻塞性肺通气功能障碍患者的心电图变化特点。方法 :食管癌患者中 ,2 0 6例伴阻塞性肺通气功能障碍者与 2 0 0例肺通气功能正常者的心电图作对照分析 ,在心率改变、左室高电压、心室肥大、劳损、肢导低电压、传导阻滞、ST -T异常、早搏、P波异常等方面进行比较分析。结果 :2 0 6例食管癌伴阻塞性肺通气功能障碍患者的心电图异常率明显高于对照组 (P <0 0 1) ,其中以心率改变、左心室高电压、心室肥大、ST -T异常等改变最显著。结论 :阻塞性肺通气功能障碍患者的心电图异常发生率与其气道阻塞的程度呈正相关 ,因此纠正缺氧和CO2 潴留是治疗心律失常的关键
Objective: To investigate the characteristics of electrocardiogram changes in patients with esophageal cancer and obstructive pulmonary ventilation dysfunction. Methods: Among the esophageal cancer patients, 206 electrocardiograms with obstructive pulmonary ventilation dysfunction were compared with 200 patients with normal pulmonary ventilation function. The changes of heart rate, left ventricular high voltage, ventricular hypertrophy, strain and limbs were analyzed. Conducted comparative analysis of low voltage, conduction block, abnormal ST-T, premature beat, and P wave abnormalities. RESULTS: The abnormal rate of electrocardiogram was significantly higher in 206 patients with esophageal cancer and obstructive pulmonary ventilation dysfunction than in the control group (P < 0.01), among which heart rate changes, left ventricular high voltage, ventricular hypertrophy, ST-T abnormalities Such changes are most noticeable. Conclusion: The incidence of abnormal ECG in patients with obstructive pulmonary ventilation dysfunction is positively correlated with the degree of airway obstruction. Therefore, correcting hypoxia and CO2 retention is the key to treat arrhythmia.
