Evaluation of Fetal Arrhythmias
Fetal arrhythmias are not uncommon. The diagnosis of a fetal arrhythmia is challenging and normally requires referral for a detailed fetal echocardiogram. The first step in the ultrasound evaluation should be distinguishing whether the arrhythmia is an irregular rhythm, a bradycardia, or a tachycardia. This can be done by evaluating the arrhythmia using simultaneous atrial and ventricular M-mod...
متن کاملEvaluation of fetal arrhythmias by echocardiography.
The normal fetal heart shows variation in rate and rhythm. Twenty three cases that fell outside the normal patterns of variation of heart rate and rhythm were evaluated by echocardiography. Ten showed atrial or ventricular extrasystoles and these were not associated with perinatal morbidity or mortality. Seven cases showed complete heart block, two in association with structural cardiac abnorma...
متن کاملFetal and Neonatal Arrhythmias.
Cardiac arrhythmias are an important aspect of fetal and neonatal medicine. Premature complexes of atrial or ventricular origin are the main cause of an irregular heart rhythm. The finding is typically unrelated to an identifiable cause and no treatment is required. Tachyarrhythmia most commonly relates to supraventricular reentrant tachycardia, atrial flutter, and sinus tachycardia. Several an...
متن کاملDetection of Fetal Cardiac Arrhythmias
Cardiac abnormalities are one of the main problems present in newborns. They can cause fetal death. If they are detected in time, it is possible to cure or to take all necessary precautions during childbirth. Our work proposes a method for detecting cardiac arrhythmias in the fetus by using digital filters and discrete wavelet transforms. On the basis of signals from the database DaIS, our meth...
متن کاملFetal Arrhythmias: A Clinical Review
Fetal rhythm abnormalities occur in 2% of pregnancies. They are usually identified by the obstetrician or midwifes after 20 weeks. There are four different methods used to assess fetal arrhythmias: scalp electrodes attached to electrocardiographic recordings, magnetocardiography (FMCG), fetal electrocardiographic recordings from the maternal abdomen, and fetal echocardiography (M-mode, pulsed-D...
