The effects of a forced withdrawal of fluid by ultrafiltration and the influences of a connected haemodialysis on the period of isometric contraction of the heart were recorded by periodical registration during the treatment. A statistically certain decrease of the LVET (-19.2%) and an increase of the PEP (+ 11.1%) were found. Since at least in the period of the isolated ultrafiltration several essential parameters of the interior milieu do not change decisively, as cause for the changes observed of the systolic intervals of the heart period the decrease of the preload is discussed. During the period of ultrafiltration on an average 15.3 +/- 3.3 ml of plasma water were taken per minute.
在治疗过程中，通过定期记录，观察了超滤强制脱水的效果以及串联血液透析对心脏等长收缩期的影响。发现左室射血时间（LVET）有统计学意义的下降（-19.2%），预射血期（PEP）增加（+11.1%）。由于至少在单纯超滤期间，体内环境的几个重要参数没有决定性变化，因此讨论了心脏收缩间期变化的原因是前负荷降低。超滤期间平均每分钟去除15.3±3.3毫升血浆水。
