[摘要] 目的：探讨利用心电图(ECG)Ⅰ导联R波的高度+S波的深度估测肺动脉收缩压(PASP)的价值。方法：选择60例先天性左向右分流型心脏病合并肺动脉高压(PAH)患者，行右心导管测量前3天内按常规方法完成十二导联心电图，由同一名医生进行心电图分析并测量，按照Ⅰ导联R波的高度+S波的深=x mV，心电图x mV相当于x×10 mm Hg肺动脉收缩压的计算方法，将结果与用右心导管所测得的PASP比较。结果：用ECG检测法测定的PASP与术中右心导管测得的PASP的相关性r=0.817。结论：ECG是一种简便有效地诊断先天性心脏病合并PAH的检查方法，可为内科介入封堵术及外科手术时机提供判断，并对治疗的可行性做出初步预测。

[Abstract] Objective: To investigate the value of the electrocardiogram (ECG) Ⅰ-guided R wave height and the S wave depth to estimate the pulmonary artery systolic pressure (PASP). Methods: 60 cases of patients with left-right shunt congenital heart disease combined with pulmonary arterial hypertension were selected. The 12-lead ECG was conducted within 3 days after right heart catheterization, in order to determine PASP. And the same doctor was assigned to measure and analyze ECG. The method of ECGⅠ-guided R wave height + S wave depth= x mV, and ECG x mV was equivalent with x ×10 mm Hg pldmonary artery pressure was used, the result was compared with PASP which was measured by right heart catheter. Results: The PASP values were determined by the methods of right heart catheterization and ECG detection, the correlation of the two methods (r was equal to 0.81). Conclusion: The ECG is a simple and efficient method which can be used for diagnosis of congenital heart disease combined with pulmonary arterial hypertension, and provide judgment of time for surgical operation and intervention blocking operation of internal medicine, also provide the preliminary evaluation for further feasibility of treatment ......
