浅析急性前壁心梗与下壁心梗心律失常对预后的影响【摘要】目的探讨并分析急性前壁心肌梗死（心梗）与下壁心梗心律失常对预后的影响。方法此次研究的对象是选择98例心梗患者，将其临床资料进行回顾性分析，并按病发部位分为前壁心梗组（48例）和下壁心梗组（50例）。所有患者在100ml生理盐水中加入100万～150万U尿激酶，并在30min内采用静脉滴注的方式输入到患者体内。采用pm8000型参监护仪对患者的心律状况进行连续3d的监测。对比两组患者预后。结果前壁心梗组发现陈旧性心肌梗死14例，占29.17%；下壁心梗组发现陈旧性心肌梗死6例，占12.00%。前壁心梗组出现陈旧性心肌梗死患者的比例明显高于下壁心梗组（P<0.05）。前壁心梗组出现28例心律失常现象，其中3例患者因心律失常死亡，心律失常发生率为58.33%，死亡率为6.25%。下壁心梗组出现32例心律失常现象，6例患者因心律失常死亡，心律失常发生率为64.00%，死亡率为12.00%。下壁心梗组心律失常发生率及病死率均高于前壁心梗组（P<0.05）。结论急性前壁心梗与下壁心梗心律失常对预后有显著影响。【关键词】心肌梗死；心律失常；预后Abstract:ObjectiveToinvestigateandanalyzetheprognosisofacuteanteriormyocardialinfarction(AMI)andinferiormyocardialinfarction(MI)arrhythmia.Methodsthesubjectsofthisstudywere98patientswithmyocardialinfarction.Theclinicaldataofthepatientswereanalyzedretrospectively.Theywerepidedintotheanteriormyocardialinfarctiongroup(48cases)andtheinferiorwallmyocardialinfarctiongroup(50cases)accordingtothelocationofthedisease.Allpatientswereadded1millionto1million500thousandUurokinasein100mlphysiologicalsaline,andwereinjectedintothepatientsbyintravenousdripat30min.Thecardiacrhythmofpatientswasmonitoredcontinuouslyfor3Dbypm8000typemonitor.Theprognosisofthetwogroupswascompared.Results14casesofoldmyocardialinfarctionwerefoundintheanteriorwallinfarctiongroup,accountingfor29.17%;6casesofoldmyocardialinfarctionwerefoundintheinferiorwallinfarctiongroup,accountingfor12%.Theproportionofpatientswitholdmyocardialinfarctionintheanteriorwallinfarctiongroupwassignificantlyhigherthanthatinthelowerwallinfarctiongroup(P<0.05).Therewere28casesofarrhythmiaintheanteriormyocardialinfarctiongroup,ofwhich3patientsdiedduetoarrhythmia,theincidenceofarrhythmiawas58.33%,andthemortalityratewas6.25%.Therewere32casesofarrhythmiaintheinferiorwallinfarctiongroup,and6patientsdiedduetoarrhythmia.Theincidenceofarrhythmiawas64%andthemortalityratewas12%.Theincidenceofarrhythmiaandfatalityrateininferiorwallmyocardialinfarctiongroupwerehigherthanthoseinanteriormyocardialinfarctiongroup(P<0.05).Conclusionacuteanteriorwallinfarctionan
