长期血透病人常见室性心律失常(VA),127例经48小时Holter监测的病人,76%有VA,21%有Lown氏分级4A或4B级心律失常,2%有室性早博(PVC)≥2次/h。血透有致心律失常作用,尤其是对患有频发或复杂VA的病人。这些现象和左室功能不全(LVD、16%)、左室肥厚(LVH、37%)、缺血性心脏病(IHD、14%)的较高发病率,促使作者评价每种因素对4年死亡率的影响。病人和方法LVD的标准:左室舒张末期指数≥32mm/M~2,心胸比例≥0.55;左室舒张末期缩短分数<25%。LVH指室间隔或左室后
Long-term hemodialysis patients with common ventricular arrhythmias (VA), 127 cases Holter monitoring 48 hours, 76% had VA, 21% had Lown’s grade 4A or 4B arrhythmias, 2% had ventricular premature beats (PVC ) ≥2 times / h. Hemodialysis has arrhythmogenic effects, especially in patients with frequent or complex VA. These phenomena and the higher prevalence of left ventricular dysfunction (LVD, 16%), left ventricular hypertrophy (LVH, 37%) and ischemic heart disease (IHD, 14%) prompted the authors to evaluate the effect of each of these factors on 4-year The impact of mortality. Patients and methods of LVD criteria: left ventricular end-diastolic index ≥ 32mm / M ~ 2, cardiothoracic ratio ≥ 0.55; shortening of left ventricular end-diastolic score <25%. LVH refers to ventricular septum or left ventricular
