Fetal magnetocardiogram waveform characteristics

The fetal magnetocardiogram.

In magnetocardiography (MCG) the magnetic field, produced by the electrical activity of the heart, is measured. This paper presents the preliminary results of the human fetal magnetocardiography (FMCG). The MCG of an adult heart was first recorded by BAULE and McFEE [1]. Recently, several research groups have utilized the superconducting quantum interference device (Squiü) in recording the MCG ...

The Reliability of the Fetal Magnetocardiogram

fMRI , PET and NIRS 3 - 3 - 14 : Fetal magnetocardiogram of cases of non - immune fetal hydrops of non - cardiovascular origin

Non-immune hydrops fetalis is defined as presence of excess fluid in two or more body areas, such as the abdomen, thorax, or skin, excluding immune etiology. Major causes of non-immune fetal hydrops are fetal heart diseases and abnormal chromosome. In spite of accumulated reports of fetal magentocardiograms (FMCG) for heart diseases, FMCG for fetal hydrops of non-cardiac origin has seldom been ...

Giant fetal magnetocardiogram P waves in congenital atrioventricular block: a marker of cardiovascular compensation?

BACKGROUND Cardiogram signal amplitude is a key index of hypertrophy but has not been investigated extensively in utero. In this study, magnetocardiography was used to assess P and QRS amplitude in normal subjects and subjects with fetal arrhythmia. METHODS AND RESULTS The study cohort consisted of 68 normal fetuses and 25 with various arrhythmias: 9 reentrant supraventricular tachycardia (SV...

Fetal electrocardiogram: ST waveform analysis in intrapartum surveillance

ST waveform analysis of fetal electrocardiogram (ECG) for intrapartum surveillance (STAN) is a newly introduced method for fetal surveillance. The purpose of this commentary is to assist in the proper use of fetal ECG in combination with cardiotocography (CTG) during labour. Guidelines and recommendations concerning CTG and ST waveform interpretation and classification are stated that were agre...
