Artifacts in cardiotachographic tracings caused by infusion pumps have been recorded and are presented. Registration of the artifacts occurs in ultrasonic or abdominal EKG-tracings when the fetal signals are weak or absent. The cause of these misregistrations which can lead to faulty interpretations are an interference of the infusion pump through the general circuit. Interference from the infusion pump is registered when grounding is insufficient or when the infusion pump is in close proximity to the abdominal electrode. In the abdominal EKG technique the instruments have to be in closer proximity than in the ultrasonic technique.
已记录并展示了由输液泵导致的心动描记图中的伪影。当胎儿信号微弱或不存在时，在超声或腹部心电图描记中会出现伪影记录。这些可能导致错误解读的误记录的原因是输液泵通过总电路产生的干扰。当接地不足或输液泵靠近腹部电极时，会记录到来自输液泵的干扰。在腹部心电图技术中，仪器之间的距离必须比超声技术中更近。
