８４例急性心肌梗死患者，梗死后住院期（＜８周）心室晚电位（ＶＬＰ）总检出率为２４％。４２例前瞻性定期随访ＶＬＰ，心肌梗死后２～６天检出率为高，但未达统计学显著性。广泛前壁梗死ＶＬＰ检出率高于前（间）壁梗死（Ｐ＜０．０５）。临床单因素分析；包括心电图和动态心电图证实的Ｌｏｗｎ分级的室性心律失常，超声心动图确诊的室壁瘤形成，ｋｉｌｌｉｐ２级以上的左室功能不全和冠脉造影证实的梗死相关冠脉再通，结果除室壁瘤形成和梗死后早期左室功能不全者ＶＬＰ检出率高外．其他因素与ＶＬＰ的相关性无统计学义。
In 84 patients with acute myocardial infarction, the total detection rate of ventricular late potential (VLP) was 24% during the hospitalization period (<8 weeks) after infarction. 42 cases of prospective and regular follow-up of VLP, 2 to 6 days after myocardial infarction detection rate was high, but not statistically significant. The prevalence of VLP in the extensive anterior wall infarction was higher than that in the anterior (inter) wall infarction (P <0.05). Clinical univariate analysis; Lown-grade ventricular arrhythmias including electrocardiogram and ambulatory electrocardiographic evidence, echocardiographic confirmed aneurysm formation, left ventricular dysfunction above killip2 level and coronary artery recanalization confirmed by coronary angiography , The results in addition to the formation of wall aneurysm and infarction early left ventricular dysfunction, the high detection rate of VLP. The correlation between other factors and VLP was not statistically significant.
