INTRODUCTION
Time voltage area of QRS is a parameter that showed a close association with modifications in endoventricular volume. The aim of the study was to investigate the efficacy of this parameter in identifying progressive reduction in circulating blood volume (BV) during haemodialytic treatment (HT).
MATERIAL AND METHODS
Thirteen uraemic patients were studied. XYX like leads were monitored before, during and after HT. Summation of areas of each QRS complex was named QRS total area (TA).
RESULTS
Increase in QRS TA and decrease in BV were found after vs. before HT. Progressive increase in QRS TA is strongly linked to a progressive reduction of BV during HT.
CONCLUSIONS
THESE FINDINGS ENCOURAGE USE OF ECG MONITORING DURING HT WITH A DUAL PURPOSE: rhythm and haemodynamic control. In fact, excessive or insufficient subtractions of water, with consequent hypotensive or cardiorespiratory crisis, are the most frequent complications in these patients.
简介
QRS 时限电压面积是一个与心室内容积改变密切相关的参数。本研究旨在探讨该参数在识别血液透析治疗期间循环血容量（BV）进行性减少中的有效性。
材料与方法
共研究了 13 例尿毒症患者。在血液透析治疗前、治疗中和治疗后监测 XYX 样导联。每个 QRS 综合波的面积总和命名为 QRS 总面积（TA）。
结果
与血液透析治疗前相比，血液透析治疗后 QRS TA 增加，BV 减少。血液透析治疗期间 QRS TA 的进行性增加与 BV 的进行性减少密切相关。
结论
这些发现鼓励在血液透析治疗期间使用心电图监测，具有双重目的：即节律和血液动力学控制。事实上，这些患者最常见的并发症是水的过度或不足扣除，导致低血压或心肺危机。
