Abstract:
In medical field the disease diagnosis is often made based on the knowledge and experience of the medical practitioner. Due to this there are chances of errors, unwanted biases and also takes longer time in accurate diagnosis of disease. In case of heart disease, its diagnosis is most difficult task. It depends on the careful analysis of different clinical and pathological data of the patient by medical experts, which is complicated process. Due to advancement in machine learning, computer and information technology, the researchers and medical practitioners in large extent are interested in the development of automated system for the prediction of heart disease. ECG consists of various waveforms of electric signals of heat .To process the ECG signal we will generate a multi-layered learning algorithm using a Learning vector Quantization (LVQ) neural network with generalized delta rules under supervised learning. The neural network in this system accepts 13 clinical features as input and predicts that there is a presence or absence of heart disease in the patient, along with different performance measures.
Keywords: Heart disease, Learning Vector Quantization(LVQ) , electrocardiogram (ECG), myocardial ischemia , myocardial infarction.
I. INTRODUCTION
The heart is the organ that pumps blood over blood vessels to different body parts, with adequate proportion of oxygen and other essential nutritional
The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.
Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.
Heart is associated to cardiovascular system, heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries
Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.
The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps spread out salts, enzymes, urea, nutrients, hormones and heat across the body.
Walking up to the Fort Worth convention center and looking at the size of the building, it blew my mind away. I couldn't believe I made it to nationals for tumbling! When I touched the stadium doors, I felt the feeling of a shock up my spine. That was when everything finally started to sink in. As I walked in I noticed that the place looked really packed, and I knew there was no room for error. Thankfully, no one was allowed to go into warm ups besides your coaches. This allowed all my nerves to go away. As I put my first step down on the stadium floors I get that amazing feel of the red, white, and blue velvety tumbling floor. I am reminded of my gym back in Oregon, and why I was there representing team Oregon. About two in a half to three
The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).
The human heart beats about one hundred thousand times per day, and two and a half billion times over a lifetime. The heart is responsible for pumping blood to the organs, tissues, and cells throughout the body. Blood sends nutrition and oxygen to the cells and carries waste products and carbon dioxide out of the body (From The Heart, 2002).

Physicians are a crucial part of the healthcare team that aids in healing and betterment of all aspects of patient care. However, there is a prevalence of between five and fifteen percent of physician that suffer from a part of impairment that affects their position and can affect patient care (Griffith). Physician impairment can range on a spectrum from alcohol abuse to depression. It is important to address these concerns for proper patient safety. In order to effectively diagnose and provide treatment, it is important that all members of the medical staff, administration and the board work together to provide aid to the concerning physician.
Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.
Heart diseases are one of the most life threatening disease in the world now a days. The common method for diagnosing cardiac diseases is ECG. ECG is simple, non-invasive and cost effective tool for diagnosing purpose. It is important to classify the beats properly to find out the arrhythmia. Classification of heart beat is tedious and time consuming job therefore there is need of automatic classification which assist cardiologist.
The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.
The heart is described as the most valuable organ in the body. The function of the heart is to pump blood throughout the body. The heart works to pump and circulate all of the materials our body needs to operate properly. The right side of the heart receives de-oxygenated blood from the body. The blood rides through the Tricuspid Valve into the Right Ventricle. After that, it pumps through the Pulmonary Valve into the Pulmonary Artery. This is where the de-oxygenated blood is taken to the lungs to get oxygen.
