为了明确左心前导联上U波极性与心肌灌注和左心室功能的关系,对63例有临床和心电图证据证明曾患前壁心肌梗死(MI)的病人,进行了铊~(201)心肌闪烁造影和锝-99m心室造影。方法:63例MI患者在MI发作后6—8周,进行铊~(201)运动闪烁造影和锝-99m心室造影。所有病人皆系首次患MI,除煎壁导联外,其余导联皆无异常Q波。其中男58例,女5例,平均年龄52岁。排除伴左、右束支阻滞或预激综合征的患者。正常对照组12例,皆系冠脉造影正常,铊运动闪烁造影正常,左心室功能正常者。男7例,女5例,平均年龄49岁。根据V_4—V_6导联U波的极性,将病人分为3组:U波直立组16例,每例至少有2个导联U波高于0.5mm;U波倒置组29例,皆倒置深度超过0.5mm;U
To clarify the relationship between U wave polarity in the left anterior heart and myocardial perfusion and left ventricular function, 63 patients with clinical and electrocardiographic evidence of anterior myocardial infarction (MI) Scintigraphy and technetium-99m ventriculography. Methods: Sixty-one to eight-week post-MI episodes of 63 MI patients underwent thalidomide 201 kinetic scintigraphy and technetium-99m ventriculography. All patients were the first time suffering from MI, in addition to frying wall lead, the other leads were normal Q waves. There were 58 males and 5 females, with an average age of 52 years. Patients with left or right bundle branch block or WPW syndrome were excluded. Normal control group of 12 cases, all Department of Coronary angiography normal, thallium motor scintigraphy normal, normal left ventricular function. 7 males and 5 females, with an average age of 49 years. The patients were divided into 3 groups according to the polarity of the U-wave of V_4-V_6 lead: 16 cases of U wave erection group, at least 2 lead U wave of each case was higher than 0.5mm; U wave inversion group of 29 cases, all inverted depth More than 0.5mm; U
