| 摘 要： | 根据１３２例患者冠脉造影（ＣＡＧ）结果，结合临床诊断进行分组并分别从体表静息标准１２导联心电图上测量得出ＱＴ间期离散度（ＱＴｄ）与ＱＴｃ间期离散度（Ｑｔｃｄ）。统计学处理结果显示：ＱＴｄ、ＱＴｃｄ在冠脉正常组（Ｃ组）分别是２２．７±１９．７ｍｓ与２８．０±１５．９ｍｓ，冠脉病变组（Ｂ组）分别是３６．４±１６．６ｍｓ与４１．０±１７．５ｍｓ，与前组比较有显著差异（Ｐ＜０．０１）。急性心肌梗死组（Ａ组）ＱＴｃ、ＱＴｃｄ分别是６４．８±２５．４ｍｓ、７３．１±２９．４ｍｓ，与前两组比较均有明显差异（Ｐ＜０．０１）。结果显示：不但急性心肌梗死组ＱＴｄ增大，而且冠脉病变组ＱＴｄ也增大。故认为心肌缺血是ＱＴｄ增大的重要原因之一，且可能与缺血产生速度和严重程度有关。

| Abstract: | QT interval dispersion (QTd) defined as QTmaximum minus QTminnium, mea-sured from the 12 lead EDG reflects regional changes in ventricular recovery and is increased during theearly hours after myocardial infarction.To study the degree of ischemia-induced dispersion of ventric-ular recovery in CAD patients(pts.),we analyzrd changes in QTd in 132pts.all pts underwent percu-tanous coronary angiography(CAG).Of the 132 pts.46 had AMI,40 had coronary artery stenosisl(>50% in diameter,CA+)and 46 were considered normal or no significant lesions(CA-).Mean QTd in pts.with AMI.CA+ and CA-was 64.8+25.4ms,36.4+16.6ms,and 22.7+19.8ms respectively.There were signeficant difference in QTd between pts.with AMI and CA-(P<0.001),and between pts.with CA+ and CA-(P<0.0l).This study revealed that increased QTd occurs not only in pts.with AMI,but also in pts.withCA+, reflecting alterations in ventricular recovery due to ischemia. |
