急性心肌梗死碎裂QRS波发生情况与梗死部位及室性心律失常的关系

Relationship between fragmented QRS complex and ventricular arrhythmia in patients with acute myocardial infarction

目的:探讨急性心肌梗死(AMI)患者心电图碎裂QRS波(fQRS)发生情况与梗死部位及室性心律失常的关系。方法:回顾性分析140例AMI患者,根据入院72 h内心电图fQRS的发生情况,分有fQRS组(A组),无fQRS组(B组),A组又按fQRS出现的导联数分为A1亚组(出现在2个导联)和A2亚组(出现在2个以上导联)。观察不同组梗死部位分布情况及住院期间各类室早、室速、室扑/室颤的发生率。结果:A组各类室早、室速、室扑/室颤的发生率及下壁心肌梗死(MI)分布率显著高于B组(均P<0.05);A2亚组各类室早、室速、室扑/室颤的发生率及下壁MI分布率显著高于A1亚组(均P<0.05)。结论:AMI后心电图fQRS者出现情况与梗死部位及室性心律失常发生密切相关,出现(尤在多导联出现)fQRS者室性心律失常的发生率显著增加。

AIM： To explore the relationship between fragmented QRS complex （fQRS） and ventricular arrhythmia in patients with acute myocardial infarction （AMI）. METHODS： One hundred and forty patients who were diagnosed with AMI were analyzed retrospectively. According to fQRS occurrence in the first 72 h after hospitalization, patients were divided into four groups： with fQRS group （A）, without fQRS group （B）, with fQRS at two leads group （A1）, and with fQRS at more than two leads group （A2）. The incidences of all kinds of premature ventricular contraction, ventricular tachycardia and ventricular fibrillation were compared. RESULTS ： The incidences of all kinds of premature ventricular contraction, ventricular tachycardia and ventricular fibrillation in group A were significantly higher than those in group B （P 〈 0. 05 ）, and the incidences in group A2 were significantly higher than those in group A1 （ P 〈 0. 05 ）. CONCLUSION ： The occurrences of fQRS in AMI patients and ventricular arrhythmia are highly correlated, fQRS may be a predictive factor of ventricular arrhythmia in AMI patients.
