Methods We retrospectively identified 14 fetuses; 8 fetuses with PAC and 6 fetuses with PVC. Based on arterial pulse Doppler, we measured the time of 2 consecutive heartbeats including the premature contraction (VXV interval) and 2 consecutive heartbeats just before premature contraction (VVV interval). We calculated difference between VVV interval and VXV interval, and examined if we could distinguish PAC from PVC. Conclusion • This study indicates that measurements of VXV interval and VVV interval from arterial Doppler waveform by fetal echocardiography can easily distinguish PVC from PAC in utero. • This simple method has the potential to become an effective screening method to select the fetuses with PVC requiring further assessment at the fetal cardiac center.
