From: Standardization of the PQRST Waveform and Analysis of Arrhythmias in the Fetus Using Vector Magnetocardiography

Figure 6

Vector magnetocardiograms of a 34-wk-old fetus with congenital 2:1 atrioventricular block, which had already been diagnosed by fetal echocardiography, but prolonged QT interval (QTc = 470 ms) was first diagnosed by fetal magnetocardiography. The diagnosis was confirmed after birth by electrocardiography. The arrows indicate p waves, half of them being located at the peak of T waves.
