摘　　要：目的探讨原发性高血压患者V，导联P波终末电势（PTFV1）改变的临床意义。方法选择80例原发性高血压患者．其中男性58例，女性22例；年龄23～80岁，平均年龄50岁。比较心电图上PTFVl≤-0.04mm·s的原发性高血压有左心房扩大的患者40例（观察组）和无左心房扩大的患者40例（对照组）的负向P波情况；心脏彩色超声检测比较两组患者的左心房扩大情况、左心室舒张功能E／A比值等。结果与对照组比较，观察组负向P波的时限明显增宽而有切迹，且余导联P波时限增宽。心脏彩色超声检查左心房均有不同程度的增大，并且左心室舒张功能（E／A比值）均有不同程度的减低：对照组中有37例患者的左心房均未增大，患者左心室舒张功能（E／A比值）出现减低的情况很少；两组差异均有显著统计学意义（P〈0.01）。结论町FV，≤-0.04mm·s且负向P波的时限宽有切迹，则提示原发性高血压患者发生左心房扩大。Objective To evaluate the changes clinical significance of P-wave terminal force of VI（PTFV1） in patients with primary hypertension. Methods A total of 80 patients with primary pertension were enrolled, which included 58 males and 22 females, aged 23 - 80 years old with mean age of 50. The negative P-wave were comparied between 40 primary hypertension partients of ECG PTFV1≤ - 0.04 mm·s with left atrial dilatation（observation group） and 40 of ECG PTFVI ≤ - 0.04 mm·s without left atrial dilatation （control group）. The left atrial dilatation, left ventricular diastolic function E / A ratio by echocardiography were compared between 2 groups. Results Compared with control group, the negative P-wave duration of observation group was significantly wider and with notch; the left atrium in various degrees were increased by color ultrasonography, and left ventricular diastolic function（E / A ratio） were reduced in different levels; The left atriums of 37 patients in control group were not increased, rarely showed E / A ratio reduced. There were significant differences between 2 groups（P 〈 0.01）. Conclusion It is suggested that PTFV1 ≤ - 0.04 mm·s and negative P-wave duration width notch, left atrial dialatation is happened in patients with primary hypertension.
