摘要：目的：探讨肺心病患者在不同时期时心电图变化的演变规律及其临床意义。方法:对120例慢性肺心病患者的临床资料进行回顾性分析并对具有突出特点的而变化进行分析。结果:慢性肺心病心、肺功能失代偿期患者与心、肺功能代偿期患者在肺型P波、窦性心动过速、房性、室性心律失常及II、III、avF 导联ST-T的改变率上存在的差异显著(p<0.05)；而在QRS电轴右偏或胸导联顺钟向转位、肢导低电压和RV1+RV5≥1.05mV的出发生率方面显著差异(p<0.05)。结论:临床工作者应高度重视慢性肺心病早期患者心电图中ST-T的改变和严重的心律失常出现等情况，早期改善患者心肌缺氧的状况，减少心肌损伤以求降低该病死亡率。

Abstract:Objective:To investigate pulmonary heart disease patients at different times when the electrocardiographic changes in evolution and its clinical significance. Methods:120 cases of chronic pulmonary heart disease patients with the clinical data were retrospectively analyzed and has outstanding characteristic and variation analysis. Results:in chronic pulmonary heart disease, and pulmonary function in patients with decompensated heart, lung function in patients with decompensated pulmonary P wave, sinus tachycardia, heartbeat atrial, ventricular arrhythmias and II, III, avF lead ST-T the rate of change of the difference significant (p<0.05); while in the QRS axis right or chest lead clockwise rotation, limb mediated by low voltage and RV1+RV5≥1.05mV the incidence of significant difference (p<0.05). Conclusion:clinicians should pay great attention to chronic pulmonary heart disease in patients with early electrocardiogram ST-T change and serious arrhythmias appear etc, early improvement in patients with myocardial hypoxia condition, reduce myocardial injury in order to reduce the disease mortality.
Key words:evolution of the clinical significance of electrocardiogram in patients with chronic pulmonary heart disease
