Simson等根据体表心电图经放大、适当滤波后所得QRS晚电位(LP),于1981年报道了LP与室性心律不齐的关系。但目前人们对LP与左心室瘤、左心室机能的关系尚无明确认识。作者根据52例心肌梗塞患者的心电记录,探讨了LP与室忙心律失常及左心室机能的关系。对象:以急性心肌梗塞发病后5年内检出LP的52例70次记录为对象。患者年龄36～84岁(平均66岁),包括广泛性前壁梗塞18例,下壁梗塞26例,心内膜下梗塞6例,侧壁梗塞26例,不含束支阻滞、房颤和杂音在1.0μV以上的病例。在研究过程中,作者选择其
Simson et al. Reported a relationship between LP and ventricular arrhythmia in 1981 based on the magnification of the body surface electrocardiogram and the resulting filtered QRS late potential (LP). However, there is no clear understanding of the relationship between LP and left ventricular aneurysm and left ventricular function. The authors based on 52 patients with myocardial infarction ECG, to explore the relationship between LP and ventricular arrhythmias and left ventricular function. PARTICIPANTS: Fifty-two records of LP were detected 70 times within 5 years after onset of acute myocardial infarction. Patients aged 36-84 years (mean, 66 years) included 18 extensive anterior infarcts, 26 inferior infarcts, 6 subendocardial infarcts, 26 lateral infarcts, and no bundle branch block, atrial fibrillation Cases with noise above 1.0μV.
