室性早搏（PVC）是胎儿超声心动图发现的第二种最常见的异位。PVC被认为是相对良性的，但在婴儿中，PVC与室性心动过速（VT），潜在的心脏病或长QT综合征（LQTS）相关，所有这些都有更谨慎的预后。1，2胎儿超声心动图可以评估PVC频率，以及PVC的早产（耦合间期），但只有胎儿心磁图（fMCG）可以评估胎儿的心跳到心跳心律模式和心脏时间间期，如P，PR，QRS和QTc间期。我们对44项fMCG研究进行了回顾性单中心描述性审查，这些研究被确定为显示PVC，这些研究来自威斯康星大学麦迪逊分校医学物理系生物磁学实验室于2010年至2020年在胎龄15至40周的胎儿中进行的280项首次研究。280项研究中有6项因技术质量而被排除。fMCG记录和测量如先前报道的那样进行。第1、3条
Premature ventricular contractions (PVCs) are the second most common form of ectopy found with fetal echocardiography. PVCs have been considered relatively benign, but in infants, PVCs are correlated with ventricular tachycardia (VT), underlying heart disease, or long QT syndrome (LQTS), all of which have a more guarded prognosis. 1, 2Fetal echocardiography can assess PVC frequency, as well as the prematurity of the PVC (coupling interval), but only fetal magnetocardiography (fMCG) can assess beat-to-beat heart rhythm patterns and cardiac time intervals of a fetus, such as P, PR, QRS, and QTc intervals. We performed a retrospective single-center descriptive review of 44 fMCG studies that were identified as showing PVCs, from among 280 first-time studies performed in the Biomagnetism Laboratory at University of Wisconsin-Madison Department of Medical Physics from 2010 to 2020 in fetuses 15 to 40 weeks gestational age. Six of 280 studies were excluded for technical quality. The fMCG recordings and measurements were performed as previously reported. 1, 3
