Cardiotocography by external telemetry and maternal ambulation has been compared to the usual recording in recumbent position. The visual interpretation extended to several items, such as technical quality, CTG scoring, contractions and foetal activity, which were interpreted for single groups of gestational age and diagnosis. A questionnaire of the patients joined with this study, referring to the acceptance of cardiotocography, definitely voted for the telemetrical method. As to the valuation of the cardiotocograms (CTGs), it was necessary to consider a slight restriction of the undulation of the foetal heart rate by telemetry. Referring to the technical quality of the CTGs, the telemetrical method was inferior in all points while recording in recumbent position. Problems appeared to occur especially with adipose gravidas. In patients with toxaemia, we noticed a tendency to increasing systolic blood pressure combined with growing restriction of foetal undulation by telemetrical recording. The use of external telemetry with maternal ambulation at other diagnostical situations should depend only on technical quality and maternal acceptance of telemetry, since there are no differences with respect to information.
通过外部遥测技术结合孕妇活动进行的胎心宫缩图检查已与常规的卧位记录进行了比较。视觉解读涵盖多个项目，如技术质量、胎心宫缩图评分、宫缩及胎儿活动情况，针对不同孕周和诊断的单组情况进行解读。参与本研究的患者的一份关于对胎心宫缩图检查接受度的问卷，明确支持遥测方法。关于胎心宫缩图（CTG）的评估，有必要考虑遥测对胎儿心率波动有轻微限制。就CTG的技术质量而言，在卧位记录时，遥测方法在各方面都较差。问题似乎尤其在肥胖孕妇中出现。在患有毒血症的患者中，我们注意到收缩压有升高的趋势，同时遥测记录显示胎儿波动受限加剧。在其他诊断情况下，结合孕妇活动使用外部遥测技术应仅取决于遥测的技术质量和孕妇对遥测的接受程度，因为在信息方面并无差异。
