目的:探讨心电图碎裂QRS波(fQRS)对急性冠脉综合征(ACS)患者死亡率的预测价值.方法:选择诊断为急性冠脉综合征入院的患者149例,其中MI组74例,其中非ST段抬高型心肌梗死组(NSTEMI)54例;不稳定性心绞痛(UA)75例(作为对照组),分析fQRS与死亡率的关系.结果:在MI组37例(50%)出现了fQRS波,而在对照组,只有3例(4%)(P<0畅001),MI ,NSTEMI ,对照组出现病理性Q波分别为20例(27%),12例(22%),0例(0%).Ka-plan-Meier生存分析揭示出现fQRS的患者比没有出现fQRS的病人死亡率更高.结论:ACS患者中出现fQRS的病人比未出现fQRS的患者死亡率更高.

Objective] To study the predictive value of fragmented QRS complex (fQRS)for mortality in acute coronary syn-drome (ACS) .[Method] Serial electrocardiograms from 149 patients with ACS who underwent cardiac catheterization were studied .149 cases of patients diagnosed with ACS were enrolled .74 patients had MIs ,including 54 patients with non-ST-el-evation myocardial infarction (NSTEMI) ,and 75 patients had UA (the control group) .Relationship between fQRS and mortali-ty was analyzed ,as well as the relationship between the fQRS complex and the mortality .[Result] Fragmented QRS developed in 37 patients (50% ) in the MI group and only 3 (4% ) in the control group (p <0 .001) .New Q waves developed in 20 (27% ) ,12 (22% ) ,and 0 (0% ) patients in the MI ,NSTEMI ,and control groups ,respectively .Kaplan-Meier survival analysis revealed that patients with fQRS had significantly decreased death rate compared to those without fQRS .[Conclusion] Patients with fQRS of ACS had significantly decreased death rate compared to those without fQRS .
