采用时域法和三维频谱法对21例急性心肌缺血患者及12例健康人进行心室晚电位的定量分析比较，结果表明；时域法中急性心肌缺血的患者QRST，D40明显高于健康人（P＜0．01），而V40则降低（P＜0．01）；三维频谱中急性心肌缺血患者的NF值与健康人相差不大（P＞0．05）；两种方法综合使用可使VLP的判别符合率分别由38．1％和23．8％上升到52．4％；三维频谱法尚适用于有束支传导阻滞的患者。
Quantitative analysis of ventricular late potentials in 21 patients with acute myocardial ischemia and 12 healthy subjects by time-domain method and three-dimensional spectrum method showed that QRST and D40 in patients with acute myocardial ischemia in time domain were significantly higher than those in healthy (P <0.01), while V40 decreased (P <0.01). NF in acute myocardial ischemia in three-dimensional spectrum was similar to that in healthy people (P> 0.05) With the use of VLP can determine the coincidence rate increased from 38.1% and 23.8% to 52.4%; three-dimensional spectral method is still suitable for patients with bundle branch block.
