不同年龄成人的ST-T改变分析

Electrocardiongram ST-T changes in adult

目的分析门诊患者心电图ST—T改变，探讨心电图ST—T改变对不同年龄段不同性别患者的心脏疾患的初步诊断意义。方法选取自2012年1月至1012年10月门诊心电图出现ST—T改变的患者1000例，回顾其就诊资料及常规心电图及动态心电图或运动试验的资料。结果20。30岁心电图ST—T改变属非器质性正常或大致正常生理变异者占绝大多数（男性组占98．8％，女性组占94．4％）。31～50岁心电图ST—T改变属器质性心脏疾患者约占一半（男性组占55．5％，女性组占40．5％）。50岁以上年龄组心电图ST—T改变属器质性心脏疾患的占大多数（男性组占90．24％，女性组占87．91％）。随着年龄增加，器质性心脏的发病率增加，尤其同时患有糖尿病、高血压等其他疾病者。结论随着年龄增加，器质性心脏疾患的发病率增加，ST—T改变有助于提示患者可能有器质性心脏病，但必需结合具体临床资料进行分析。

Objective To analyze the ST-T changes in ECG of clinic patients and discuss the clinical diagnostic significance of ST-T changes in ECG from patients with heart disease of different ages and different genders. Method We selected 1000 cases with the ST-T changes in ECG from Jan. 2012 to Oct. 1012, and reviewed their clinical data, ECG, dynamic electrocardiography and exercise test data, and analyzed the diagnostic results using the statistical methods in different groups. Result The majority of ST-T changes in ECG for patients at 20-30 years old were non-organic normal or nearly normal physiological variations （male 98.8%, female 94.4%）. For the patients at 31-50 years old, ST-T changes in ECG which belongs to organic heart disease accounted for about half of the group （male 55.5%, female 40.5%）. For the patients above 50 years, the majority of ST-T changes in ECG were organic heart disease （male 90.24%, female 87.91%）. With the increase of age, the incidence of organic heart disease increased, especially when the patient was suffering from diabetes, hypertension and other diseases. Conclusion In different age groups, the clinical diagnosis of organic heart disease by ST-T changes in ECG should be careful and confirmed in combination with specific clinical history, symptoms and other clinical examination data. With the increase of age, the incidence of organic heart disease increased.
