Cardiology The human heart has a special characteristic, it has its own electrical impulse, which allows it to beat normally outside of the human body as long as it has sufficient oxygen levels. The term cardiology refers to the medical branch which focuses on disease and irregularities of the heart. A cardiologist focuses on the individual area of the body that is the heart and these doctors focus on preventing and treating illnesses of the whole heart or single vessels or arteries. Technology in all medical fields are constantly improving and becoming reliable. Within the past two decades there has been a multitude of advancements in the field of cardiology. An example of the improvement made in the field of cardiology include the invention of artificial organs. According to Yukiyasu Sezai, “Progress in several types of artificial organs in the cardiovascular field … have significantly contributed to advancements in cardiac surgery” (318). Examples of these artificial organs include the following: percutaneous cardiopulmonary systems, ventricular assist devices, nonpulsatile flow pumps, and artificial hearts. Percutaneous cardiopulmonary systems allows the patient to regulate pressure and temperature of blood, as well as oxygen levels. This method of control is used widely due to the cost, both the device used and instillation, being significantly lower than the cost of an artificial heart, and the uncomplicated form of control. Two types of ventricular assist devices-
3. Describe the blood flow of the heart and the correct locations the blood enters and exits.
Based off of the case study regarding a 47 year old man who has recently been diagnosed with a heart disease known as CAD; I decided to further my research on this topic because it was intriguing to discover all heart diseases including coronary heart disease are taking the lives of countless individuals each year in our nation. A tremendous number of more than 13 million Americans (2005-2015, WebMD).
Heart diseases also known as cardiovascular diseases are various conditions types that may interfere with the function of the heart. These condition types include atherosclerotic also known as coronary artery heart disease which is shown to affect arteries leading to the heart, the heart valve disease which affects the functionality of valves in regulating in and out of the blood flow to the heart. Cardiomyopathy affects the squeezing of the heart muscles. Arrhythmias also called the heart rhythm disturbances affects the electrical conductions. There are also heart infections which are resulted by structural problems of the heart which usually develops before birth. (Wedro)

Cardiology is, by definition, the study of the heart and the cardiovascular system. As a paramedic, you must be able to read a Cardiac monitor; understand and interpret the
Someone could feel okay and happy with them self if they killed somebody because of an eye. The narrator in Edgar Allen poes "The Tell-Tale Heart" kills his own roommate who is a elderly old man because his roommates eye intimidate him. He loves the man dearly but he just can't stand his eye. The man did no wrong to him. He killed his roommate and might be trying to plead insanity. The narrator should get charged with murder and she get sent to jail for killing the old man.
There are two types of artificial hearts, the first being a pump that is connected to the patient’s circulatory system; it maintains life when the patient’s heart is stopped for the surgeons to be able to operate on the heart. The second type is a self-contained mechanical heart that sits completely in the patient’s chest cavity. This second type of heart is known as a “VAD” pump which pumps blood from the left ventricle to the aorta. Most mechanical hearts use a centrifugal pump, which is quieter, uses less energy and lasts longer than the piston type mechanical hearts. The centrifugal pump produces a constant flow of blood around the body; therefore the patient will not have a
In the rougher neighborhoods of Queens where I did a majority of my growing up, repression is survival. Everyone keeps their heads down, shuffles to work in the morning, and shuffles back at night. There’s a pervasive culture of tragedy; it is everywhere: families torn apart by deportations, young men taken by gang violence and guns, and young children missing mothers and fathers. But, to survive, it must be as if none of that matters. Shuffle to work, shuffle back.
This article will explore your heart's anatomy. We'll describe its exterior, including the arteries and veins that supply blood to the muscle. We'll also describe the organ's interior, including the chambers, valves, and blood flow. Lastly, you'll learn how its electrical system helps ensure its proper function.
Heart murmurs are swishing or whooshing sounds created by turbulent blood with each heartbeat. This sound is usually observed through auscultation of the heart with a stethoscope. Many times, this sound is indicative to underlying cardiac abnormalities. However, the sound can be benign and many live without incident and asymptomatic. Abnormalities to the structure of the heart may be the main cause. These malfunctions can be congenital in nature or may come with stress on the heart and valves. Common structural conditions are stenosis of the heart (mitral, aortic, tricuspid, pulmonary), regurgitations (mitral, aortic, tricuspid), septal defects and patent ductus arteriosus. Damage to the structure may also be caused by myocardial infarction,
Try to imagine how different life would be without modern medical technology. Many of these improvements involved the combined application of engineering and biological principles to the traditional medical arts, giving physicians new perspectives on how the body works and new solutions. From providing better diagnostic tools and surgical procedures to creating more effective replacements for the body's own tissues and organs, engineering helped the 20th centuries doctors successfully address such long-standing problems of human health such as heart disease and with infectious diseases.
Since 19th century, scientists have tried to develop a device which could temporary replace heart action (SynCardia n.d). In 1957, at Cleveland Clinic, DR. Kolff and Dr. Tetsuzo Akutsu implanted an artificial heart in animals such as dog which survived for roughly 90 minutes (SynCardia n.d). On December 1982, doctors put a permanent artificial heart in to Dr. Barney Clark , 61 years old dentist, as a result, he lived for 112 days, however, he was suffering due to hard condition after the operation (SynCardia n.d; Lewis 2016). After in 2004, the CardioWest became the first and only total artificial heart which approved by FDA and the name of SynCardia temporary CardioWest™ Total Artificial Heart was given within approval process (SynCardia
So we all know that when that when a fetus is developing that the heart is the first organ that forms and in that heart contains four different regions. Where's the two ventricles in the to Atria's the right sides on the left side and those contain different cells that helps our body perform the different functions and it means. Such as pumping blood and moving oxygen and getting rid of everything that we need to get rid of and doing what it needs to do to make it so that we can live. Now when there's a problem in the heart there are different ways that the medical community has been able to help us such as with pacemakers and even artificial things in our hearts to help us. Unfortunately it's not always a perfect fix. There are things called
This paper will present to you the current developments in the area of creating artificial hearts. Artificial hearts are synthetically made devices designed to replace flesh and blood hearts when they no longer work to their full capacity. Researchers have created many artificial hearts that are suitable for assisting the heart when half of the heart is no longer functioning well, but they have not yet created an artificial heart that can function in place of a heart for a person’s entire life. This topic is interesting and gives scientists a better understanding of how our heart functions and how to replicate those functions to prolong people’s lives. This paper will present the research in a chronological order of discoveries.
In our world organisms occupy a sliding scale of complexity. On one hand we have the single cell organisms, where all necessary functions for their life are carried out within that one cell. At the other extreme we have extremely complex multicellular organisms, of which humans are perhaps the cardinal member. Obviously, with increased capacity comes increased abilities. Complex organisms are able to manipulate their environment to a greater extent then their simpler cousins. While this has a lot of advantages, it also presents interesting biological problems. With the increased complexity multicellular organisms must have systems to deliver nutrients, signaling molecules, and biochemical building blocks to every cell. In
