1、湖南師范大學(xué)本科畢業(yè)論文考籍號：XXXXXXXXX姓名：XXX專業(yè)：醫(yī)藥學(xué)臨床醫(yī)學(xué)論文題目：冠狀動脈病變嚴重程度、病變位置及冠心病介入治療對ＱＴ離散度的影響指導(dǎo)老師：XXX二〇一一年十二月十日摘要：探討冠狀動脈病變嚴重程度、病變位置及冠心病介入治療對ＱＴ離散度(QTd)及校正ＱＴ離散度（QTcd）的影響。入選159例已行冠脈造影術(shù)且心電圖及臨床資料完整的病例，按如下進行分組：（1）按病變狹窄程度分組：①無狹窄組，冠脈造影示病變狹窄50%，為31例；②輕度狹窄組，冠脈造影示病變狹窄≥50%且70%，為54例；③重度狹窄組，冠脈
2、造影示病變狹窄≥70%，為74例。（2）根據(jù)病變位置分組：①前降支組，為45例；②回旋支組，為37例；③右冠脈組，為46例。（3）根據(jù)介入治療前后分組為：①術(shù)前組，為99例；②術(shù)后組，為99例。觀察冠狀動脈病變狹窄程度、病變位置及介入治療對QTd及QTcd的影響。結(jié)果：冠脈狹窄≥70%對QTd及QTcd影響明顯，p0.05，而冠脈狹窄70%對QTd及QTcd無明顯影響，p0.05；冠脈病變所處位置對QTd及QTcd無明顯影響，p0.05；介入治療前后QTd及QTcd變化明顯，p0.05，介入治療術(shù)后與無狹窄組相比，QTd及Q
3、Tcd無明顯差異，p0.05。結(jié)論：冠脈病變所出位置對QTd及QTcd無影響，病變嚴重程度及介入治療對QTd及QTcd影響明顯。關(guān)鍵詞：冠狀動脈造影心電圖QT離散度YUANYi-qiangLIUHuai-lingMAYe-xin,etal.TheInfluenceofTheStenoses、LocationandInterventionofCoronaryArteryDisease(CAD)onQTDispersion（QTd）andcorrectedQTd(QTcd).Toinvestigatetheinfluenceof
