Abstract

The aspire of this paper is in the direction of extort the Fetal Electrocardiogram (FECG) indication from the motherrsquo;s tummy signal which is an essential signal to investigate the abnormality of the fetal heart by a general practitioner. By using the least- mean-square (LMS) filter the abdomen of the motherrsquo;s are extracted. The LMS filter is an adaptive filter, in which the FIR filter coefficients are extracted from motherrsquo;s abdomen. To calculate the fetal heart beat, the FECG based signal estimation is wanted over period. The FECG of the mother is taken at the pregnancy of 20 weeks by using this system. While considering the FECG in real time manner, the maternal woman should wear a wide belt with electrodes fitted in large manner. To separate the signals, the adaptive noise canceller algorithm is used. The adaptive noise canceller algorithm is used to analyze the collected information of the electrodes which are fitted in the belt of the womanrsquo;s abdomen. This separation is here done based on predefined values by using the LabVIEW tool. The FIR filter is designed and simulated with the help of Xilinx ISE 12.1 and is implanted by using Spartan 3 of FPGA.

Ⅰ. INTRODUCTION

The fetal health condition and abnormalities can be check by using the test (FECG) which is denoted as Fetal Electrocardiogram. This test will provides to get better treatment to the patient during pregnancy stage [8]. BY using this test, the heart beat of the fetal is also estimated with health condition. Systematic and regular checkup is needed during the pregnancy period. From this checkup the health condition and abnormalities of the fetal can be detected early and appropriate treatment or correct decision can be taken on time [5]. This paper will help the doctors to know about the fetal heart rate. Figure 1 shows the human heart structure. Fetal Heart Rate detection can also be useful in other cases, ie detection of gestation age of the baby can be detected, monitor progress of labor detection of miscarriage rate for pregnancies, and monitor and evaluation of uterine contractions, etc. For animals and humans, the heart is an important organ, which pumps blood to the circulatory system through the blood vessels. Blood gives the body with oxygen and nutrients, and also helps in the removal of metabolic wastes. The heart is located in the chest, middle compartment of the mediastinum and is shown in fig.1.

Fig.1. The Human Heart (wikepedia).

The heart is divided into four chambers: the upper part of heart is left and right atria; and lower part of heart is left and right ventricles. Commonly the right heart is formed by combining right atrium and right ventricle and their left heart is formed by combining left atrium and ventricle. Fish have two chambers, an atrium and a ventricle, and reptiles have three chambers. In a healthy heart, blood flows only in one way through the heart through the heart valves, which prevent backflow. The heart is enclosed in the pericardium, a protective sac, which contains a small amount of fluid. The three layers used to make the heart are termed as: myocardium, endocardium and epicardium.

The heart pumps blood through the body. Blood low in oxygen makes the systemic circulation and enters the blood to right atrium through superior and inferior vena cavae and it passes towards the right ventricle. Starting here it is pumped addicted to the pulmonary circulation, through the lungs where it receives oxygen and gives out the carbon-dioxide in [1]. The oxygenated blood in that case a return towards the left atrium, then it passes all the way through the left ventricle and is pumped out during the aorta to the systemic circulation in which the oxygen is used and metabolized to carbon dioxide. In accumulation the blood carry nutrients as of the digestive tract to a variety of organs of the body, at the same time as transporting waste on the way to the liver and kidneys. On the whole with every heartbeat the right ventricle pumps the identical quantity of blood interested in the lungs the same as the left ventricle pumps towards the body. Veins transfer blood on the way to the heart and hold deoxygenated blood - apart from on behalf of the pulmonary and portal veins. Arteries transfer blood apart from the heart and away from each other of the pulmonary artery cling to oxygenated blood. Their augmented distance as of the heart origin veins to enclose lower pressures than arteries. The heart contracts by the side
