摘要
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。
The late potentials in 84 cases of acute myocardial infarction were de-tected during hospitalized period. The total incidence of late potentials was 25%. In 42cases who underwent prospective detection , the highest incidence was within 2 to 6 daysafter infarction but the diference did not reach statistical significance. The incidence oflate potentials in cases with extensive anterior wall infarction was higher than that incases with anterioseptal wall infarction (P<0.05). Clinical single factor analyses wereCarred out including ventricular arrhythmia detected by ECG or AECG with Lown clas-sification , aneurysm diagnosed by UCG, left ventricular dysfunction classified by Killipclassification and infarct-related coronary artery patency confirmed by angiography. Theresult showed that only aneurysm and early left ventricular dysfunction were found to becorrelated with the presence of late potentials while other factors were not.
