妊娠34周时，一个复杂心脏畸形胎儿的心磁图记录显示了一种不寻常的胎儿心律失常，其中观察到的节律在长时间的窦性心律和交界性心律之间交替。胎心率测定显示交界性心律与呼吸性心律失常密切相关。我们推测，胎儿呼吸运动的开始和停止引起的自主神经平衡的变化是节律交替的主要原因。据我们所知，这是第一次报告胎儿交界区心律和第一次观察胎儿呼吸心律失常期间非窦性心律。
Magnetocardiographic recordings from a fetus at 34 weeks' gestation with a complex heart malformation revealed an unusual fetal arrhythmia, where the rhythm was observed to alternate between extended periods of sinus and junctional rhythms. Fetal heart rate measurement showed that the junctional rhythm was strongly associated with respiratory arrhythmia. We hypothesize that changes in autonomic balance due to the onset and cessation of fetal breathing movements were largely responsible for the rhythm alternations. To our knowledge this is the first report of a fetal junction rhythm and the first observation of fetal respiratory arrhythmia during nonsinus rhythm.
