Detection of Cardiac Anomaly From Fetal Ecg Signals

Abstract

ABSTRACT newlinePrenatal analysis and diagnosis of assorted fetal cardiac deformities are extremely crucial newlinefor managing possible obstacles with the birth process, and assessing the well being of fetus. newlineCongenital cardiac deformities are the common reason for the birth related deaths, severe newlinephysical disabilities, cognitive impairment and cerebral palsy in neonates. Early diagnosis newlineof fetal cardiac anomaly may help obstetrics to necessitate appropriate treatment during newlinepregnancy, and also can suggest appropriate future treatment to manage the well being of newlinethe fetus after birth. newlineFetal electrocardiogram is the recommended modality to detect cardiac anomaly. Fetal newlinecardiac anomaly interpretation is a challenging effort. Fetal cardiac activity can be assessed newlineby scrutinizing fetal electrocardiogram and fetal heart rate. Clinically crucial features are newlinehidden in the amplitudes and waveform durations of fetal electrocardiogram, and fetal heart newlinerate. These features are vital in fetal cardiac anomaly interpretation. Analysis of fetal electrocardiogram newlinecan also assist to make instant decision if necessary. There are many invasive newlineand non-invasive fetal electrocardiogram observation techniques, both applied to acquire newlinefetal electrocardiogram, but unfavourably some invasive methods have certain boundaries. newlineNon-invasive abdominal electrocardiogram observation has lot of recompenses over newlineexisting invasive and non-invasive observations, but it has a snag. The snag of abdominal newlineelectrocardiogram is its complex nature, due to mixtures of signal in it. It is composed of newlinehigh frequency maternal electromyogram, 50Hz power line interference, maternal electrocardiogram, newlinepatient s breathing or movement interference called baseline wander, uterine newlinecontraction and other environmental noises. Maternal electrocardiogram is a prime artifact newlinethat entirely overlaps the fetal electrocardiogram with high amplitude generally 10-30 newlinetimes stronger than fetal electrocardiogram. Entire maternal influence has to be eradicated newlineto acquire and scrutinize feta
