Prenatal Diagnosis of Fetal Arrhythmias and Assessment of Autonomic Nervous System Activity by Fetal Magnetocardiography
Magnetocardiography (MCG) is a technique that enables the noncontact, noninvasive measurement of electrocardiographic phenomena, and fetal magnetocardiography (FMCG) is extremely useful for the analysis of fetal electrocardiographic phenomena. We have used FMCG for the diagnosis and treatment of a range of fetal arrhythmias, and to perform comparative studies of autonomic nervous system activit...
متن کاملAssessment of Fetal Autonomic Nervous System Activity by Fetal Magnetocardiography: Comparison of Normal Pregnancy and Intrauterine Growth Restriction
OBJECTIVE To clarify the developmental activity of the autonomic nervous system (ANS) of the normal fetus and intrauterine growth restriction (IUGR) cases using fetal magnetocardiography (FMCG). SUBJECTS AND METHODS Normal pregnancy (n = 35) and IUGR (n = 12) cases at 28-39 and 32-37 weeks of gestation, respectively, were included in this study. The R-R interval variability was used to calcul...
متن کاملAssessment of intra-uterine growth retardation by fetal magnetocardiography
Fetal magnetocardiography allows the noninvasive registration of the prenatal cardiac electrophysiological signal. The good signal-to-noise characteristics of most biomagnetometers combined with adequate signal processing techniques generally permit the identification of the fetal deand repolarization onsets and offsets to an accuracy of 1 ms. The P wave, QRS complex and sometimes the T wave ca...
متن کاملFuture topics in fetal magnetocardiography
Since the first fetal magnetocardiogram was demonstrated by Kariniemi in 1974 [1], various groups worldwide have explored potential of investigating fetal cardiac activity using biomagnetic sensing systems and have examined the issues involved (for an overview, see [2]). In the past 25 years, fetal magnetocardiograms (FMCG) have been recorded in healthy fetuses as well as in pregnancies involvi...
متن کاملNew insights into fetal atrioventricular block using fetal magnetocardiography.
outine fetal arrhythmia assessment typically involves the se of echocardiographic modalities that demonstrate mehanical events from which electrophysiological events are nferred (1). While M-mode and Doppler-based techniques ave been used successfully to diagnose third-degree atrioentricular block (AVB), second-degree AVB, and, more ecently, first-degree AVB, our evaluation has been limited o a...
