目的：探讨心电图T波峰末（ Tp-Te ）间期对冠心病患者的临床诊断价值。方法回顾性分析2010年5月-2013年5月入住的110例心脏病患者的临床资料，其中62例为冠心病患者（ CHD组），48例为非冠心病患者（非CHD组）。对2组患者Tp-Te 间期、Tp-Te 间期离散度及J波进行测量，并对心电图进行记录。结果（1）2组V2导联Tp-Te 间期、V6导联Tp-Te 间期比较，差异具有统计学意义（ P ＜0|．05， P ＜0．01），但Tp-Te 间期离散度比较，差异无统计学意义（ P ＞0．05）；（2）不同支数冠状动脉狭窄组间V2导联Tp-Te 间期、V6导联Tp-Te间期及Tp-Te 间期离散度比较，差异均无统计学意义（ P ＞0．05）；（3）冠心病患者中，有J波组与无J波组V2导联Tp-Te 间期、V6导联Tp-Te 间期及Tp-Te 间期离散度比较，差异均无统计学意义（ P ＞0．05）。结论心电图Tp-Te 间期对冠心病的诊断具有一定的临床价值；冠脉狭窄支数或缺血性J波对Tp-Te 间期并非惟一的影响因素。“,”Objective To explore the electrocardiogram T wave end ( Tp-Te ) interval of coronary heart disease in clinical diagnostic value .Methods Retrospective analysis of May 2010 to May 2013 110 cases clinical data of inpatients with heart disease , including 62 cases of coronary heart disease ( CHD group ) , 48 cases of non-coronary heart disease ( non-CHD group).On two groups of patients T p-Te interval, Tp-Te interval dispersion and J wave measurements , and ECG recording.Re-sults (1) 2 group V2 lead Tp-Te interval, V6 lead Tp-Te interval value, the difference was statistically significant ( P 0.05) ;(3)Coronary artery disease patients, J wave group and non-J wave group V2 J wave ECG Tp-Te interval, V6 lead Tp-Te interval and Tp-Te interval dispersion,the difference was not statistically significant ( P >0.05).Conclusion The diagnostic value of ECG T p-Te interval in coronary artery disease is certain;coronary stenosis count or ischemic J wave on T p-Te interval is not the only factor .
