摘要 目的探讨静息12导联心电图碎裂QRS波群诊断非ST段抬高型急性心肌梗死中价值。方法回顾性分析我院2016年12月~2018年12月收治的104例非ST段抬高型急性心肌梗死患者的临床资料,按照静息12导联心电图检查结果将其分为碎裂QRS波群阴性组(n=34)和碎裂QRS波群阳性组(n=70),比较两组超声心动图指标及实验室检查指标。结果碎裂QRS波群阳性组左心室舒张末期内径、室壁瘤占比高于碎裂QRS波群阴性组,左室射血分数及室壁运动异常占比低于碎裂QRS波群阴性组(P<0.05);碎裂QRS波群阳性组肌酸激酶同工酶水平低于碎裂QRS波群阴性组,肌钙蛋白Ⅰ水平高于碎裂QRS波群阴性组(P<0.05)。结论静息12导联心电图碎裂QRS波群能够有效判断非ST段抬高型急性心肌梗死患者实验室检查水平、左心室舒张末期内径及左室射血分数,可为临床诊断及治疗提供有效参考依据。 Objective To explore the value of resting 12-lead electrocardiogram fragmented QRS complex in the diagnosis of non-ST segment elevation acute myocardial infarction.Methods The clinical data of 104 patients with non-ST-segment elevation acute myocardial infarction treated in our hospital from December 2016 to December 2018 were retrospectively analyzed,According to the results of resting 12-lead ECG,it was divided into a fragmented QRS complex negative group(n=34)and a fragmented QRS complex positive group(n=70).The two groups of echocardiographic indicators and laboratory tests were compared.index.Results The proportion of left ventricular end-diastolic diameter and ventricular aneurysm in the fragmented QRS complex group was higher than that in the fragmented QRS complex group,and the left ventricular ejection fraction and wall motion abnormality were lower than those in the fragmented QRS complex group(P<0.05),The levels of creatine kinase isoenzyme in the fragmented QRS complex-positive group were lower than those in the fragmented QRS complex-negative group,the level of troponinⅠwas higher than that of the fragmented QRS complex negative group(P<0.05).Conclusion The resting 12-lead ECG fragmented QRS complex can effectively determine the laboratory examination level,left ventricular end-diastolic diameter,and left ventricular ejection fraction in patients with non-ST-segment elevation acute myocardial infarction,which can provide effective clinical diagnosis and treatment reference.
