摘要
目的探讨心电图T波峰末(T_p-T_e)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T_p-T_e间期、T_p-T_e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V_2导联T_p-T_e间期、V_6导联T_p-T_e间期比较,差异具有统计学意义(P<0.05,P<0.01),但T_p-T_e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V_2导联T_p-T_e间期、V_6导联T_p-T_e间期及T_p-T_e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V_2导联T_p-T_e间期、V_6导联T_pT_e间期及T_p-T_e间期离散度比较,差异均无统计学意义(P>0.05)。结论心电图T_p-T_e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T_p-T_e间期并非惟一的影响因素。
Objective To explore the electrocardiogram T wave end（T_p-T_e）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-T_e interval,T_p-T_e interval dispersion and J wave measurements,and ECG recording.Resuits（1）2 group V_2 lead T_p-T_e interval,V_6 lead T_p-T_e interval value,the difference was statistically significant（P0.05,P0.01）,but the T_p-T_e interval dispersion,the difference was not statistically significant（P0.05）;（2） Diffe rent counts coronary stenosis group V_2 lead T_p-T_e interval,V_6 lead T_p-T_e interval and T_p-T_e interval dispersion,the difference was not statistically significant（P0.05）;（3）Coronary artery disease patients,J wave group and non-J wave group V_2 J wave ECG T_p-T_e interval,V_6 lead T_p-T_e interval and T_p-T_e interval dispersion,the difference was not statistically significant（P0.05）.Conclusion The diagnostic value of ECG T_p-T_e interval in coronary artery disease is certain;coronary stenosis count or ischemic J wave on T_p-T_e interval is not the only factor.
