目的 研究隐匿性高血压患者心脏早期损害与心电图的改变,为降低隐匿性高血压的发病率及减少心脑血管病的发生提供帮助。方法 选取2013年3月至2015年5月在我院住院及门诊确诊的135例隐匿性高血压患者为观察组,选取140例真性高血压患者为对照组,分析两组心电图的改变情况。结果 观察组T波改变率、ST-T改变率、束支阻滞率、左室肥厚率、左室面高压率明显较对照组低,差异有统计学意义（P〈0.01）。两组P波增宽率、P波双峰率比较,差异无统计学意义（P〉0.05）。随着年龄的增长,心电图异常率逐渐增加。结论隐匿性高血压患者心脏早期损害与心电图改变关系密切,P波增宽及双峰改变可能是其敏感性指标。

英文摘要：

Objective To study early heart damage and changes of masked hypertension pa- tients, provide the basis to reduce the incidence of masked hypertension and the incidence of cardio- cerebral vascular disease. Methods Select 135 cases of masked hypertension patients on March 2013-May 2015 hospitalized in our hospital and clinic diagnosis of occult group to observe group, and 140 sustained hypertension subjects were included in control group, analysis of the two groups of ECG changes. Results The T wave change rate, rate of ST-T change, bundle branch block rate, rate of left ventricular hypertrophy, left ventricular pressure ratio in Observe group was significantly lower than that in control group, the differences between the two groups was statistically significant （P 〈 0.01 ）. There was no significant difference in prevalence of P-wave broadening and prevalence of P-wave bimodal changes between control group and observe group. As the growth of age, the rate of abnormal ECG increased gradually. Conclusion It＇s Closely related to early heart damage and ECG changes sensitivity among masked hypertension patients, P wave broadening and bimodal change may be index.
