碎裂QRS波评估急性冠脉综合征的临床价值

Assessment of Clinical Value of Patients with acute coronary syndrome by Fragmented QRS Complexes

目的通过观察急性冠状动脉综合征(acute coronary syndrome,ACS)患者的心电图碎裂QRS波(Fragmented QRS complex,fQ RS)变化,探讨fQRS评估ST段抬高型心肌梗死(ST elevation myocardial infarction,STEMI)、非ST段抬高型心肌梗死(non ST elevation myocardial infarction,NSTEMI)、不稳定型心绞痛(unstable angina,UA)的临床价值。方法观察ACS患者的心电图fQRS发生率。结果 UA组fQRS发生率明显低于STEMI组、NSTEMI组(均p<0.05)。结论 fQRS用于诊断STEMI、NSTEMI有较高的临床价值,fQRS可作为鉴别UA与NSTEMI的指标。

Objective To explore the assessment of clinical value of patients with acute ST-elevation myocardial infarction（STEMI） and non ST elevation myocardial infarction（NTSEMI） and unstable angina（UA） by fragmented QRS complexes（fQRS） through observing the change of ECG fQRS of patients with acute coronary syndrome（ACS）. Methods Incidence of ECG fQRS of the patients with ACS is observed. Results Incidence of ECG fQRS of the patients with UA group is obviously lower than STEMI group and NSTEMI group after（p0.05）.Conclusion fQRS has important clinical significance on the assessment of STEMI and NSTEMI. fQRS is importent Iindicator of distinguish the UA from the NSTEMI.
