Electrophysiology of Fetal Arrhythmia
University of Wisconsin, Madison
Summary
Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow the investigators to evaluate fetal magnetocardiography (fMCG) as a new tool for the study of normal and abnormal fetal heart rate and rhythm.
Description
Purpose Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The purpose of the proposed study is to utilize fMCG, the magnetic analog of fetal ECG, to characterize the heart rate and rhythm patterns of fetuses with fetal arrhythmia or at risk of fetal arrhythmia. The study is not intended to be a pivotal study. The subject device is already cleared for clinical use for recording…
