Abstract

We show that oscillations at foetal breathing frequencies observed in foetal heart rate (FHR) tracings obtained from foetal magnetocardiogram (FMCG) recordings are often accompanied by synchronous modulation of FMCG signal amplitude. This implies an association between the FHR oscillations and foetal chest wall movements, corroborating the hypothesis that the oscillations are due to respiratory sinus arrhythmia.

摘要

我们发现，从胎儿磁心动图（FMCG）记录中获得的胎儿心率（FHR）描记图中观察到的胎儿呼吸频率振荡，通常伴随着FMCG信号幅度的同步调制。这意味着FHR振荡与胎儿胸壁运动之间存在关联，证实了振荡是由呼吸性窦性心律失常引起的这一假设。
