...ting down the rest of the body. The immune system is said to have the most critical role in the injury. It affects the lack of pathogen invaders, neutrophil recruitment and macrophage infiltration (Xiang, Yanxio, 2016).
Certain diseases can also cause the electrical system of the heart to fail, and therefore lead to cardiac arrest. One of the most infamous diseases is the coronary heart disease, it is caused by over the top severe stress. While coronary heart disease is the plaque build up in there arteries which leads to the blockage of blood flow to the heart, which over all is one of the main causes of heart attacks, can actually lead to cardiac arrest. It is all one step that leads to another step that leads up the ladder. During a heart attack some muscle cells die, and while scar tissue replaces the once healthy tissue, it damages the hearts electrical system.

- Congestive Heart Failure (CHF) In the U.S. alone, there’re approximately 5.7 million Americans who are affected by congestive heart failure and about 550,000 new cases each year . A common misconception among Americans, is that cardiac arrest and heart failure are the same – not exactly. Both conditions can be life-threatening, but heart failure refers to the incapability of the heart to circulate blood throughout the body to meet the body’s needs. Due to the inadequate blood circulation, it results the leaking of fluid from the capillaries and is where the “congestive” part of CHF comes from....

- The Left Ventricle of the Heart The left ventricle is one of the four hollow chambers of the heart. Being the largest chamber, it has an ovular shape and it occupies most of the left lateral and anterior planes of the heart. It also occupies most of the apex of the heart. The walls of the left ventricle are denser and stronger than that of the right ventricle. The thicker walls of the left ventricle support its tremendous workload of pumping blood at great pressure out of the heart. As the left atrium contracts, the mitral valve opens, which releases stored oxygen rich blood into the left ventricle.... [tags: Heart Anatomy, Health]

- Heart Attack A heart attack is damage to the heart due to decreasing blood supply (and the oxygen supply) to the part of the heart muscle. A heart attack affects cardiovascular system, this part of the system that shows these effects is the hear muscle. When a heart attack occurs a part of the heart muscle is no longer supplied with oxygen, the muscle in that area dies, cardiac arrest can then occur stopping the heart. Various lifestyle choices can cause the disease, these include; being overweight due to bad eating habits, physical inactivity, unhealthy diet, smoking, high blood pressure and a less common cause is an aneurysm which is A heart attack is caused by plaque in the coronary art...

- Cardiac arrest is one of the primary sources of mortality throughout the nation. It is estimated that over one hundred and seventy-three thousand cardiac arrests occur in Canada and the United States combined per year. An individual’s survival rate is four times higher when cardiopulmonary resuscitation (CPR) is initiated at the initial onset of cardiac arrest. Unfortunately, bystander cpr has continued to remain less than twenty percent over the past decade. It is crucial for communities to research the rationales behind why individuals refrain from interacting when patients are experiencing a cardiac event....

- Reliability Testing – by Alexander Wassell 11-30-13 Executive Summary Sudden cardiac arrest is a health problem, claiming over 450,000 lives every year in the US. Sudden cardiac arrest is reversible, but only if treated within minutes with the aid of an electrical cardioverter shock via an automated external defibrillator (AED) or with an AED defibrillator. (Sudden Cardian Arrest, n.d.). Sudden Cardiac Arrest (SCA) is an electrical problem caused by electrical malfunction of the heart that results in no blood flow to the body and brain usually caused by an abnormal heart rhythm called ventricular fibrillation (VF).The most effective way to treat Sudden Cardiac Arrest (SCA) is through defibri...

- ... A study examined by The New York Times shows a positive correlation between Taser use and cardiac arrest, stating that these devices have the potential to cause irregular heart rhythms especially if fired at the chest. In the case of Robert Dziekanski, a Taser was applied to his body five times causing him to go into cardiac arrest. In many cases of Taser-related fatalities in Canada, these devices were fired more than once. This suggests that the officers using the Tasers might be considered more reliable for the fatalities than the Tasers themselves.... [tags: taser, target, arrest, resisting, crime, ciminal]

- There are many diseases in the world that involves millions of people dying every day by contagion, genetics, and many other components. Bradycardia is the development of a medically irregular, slow heartbeat, and it’s a disease most commonly seen in elderly people. Athletes who usually exercise come upon this problem because of their fit anatomy or bodily structure. However, people who are healthy, young, and fit usually have slow heart rates and it’s not in any way harmful to their self being.... [tags: Heart, Cardiology, Heart rate]

- The heart has autorhythmic fibers that enable it to beat independently. “Ischemia usually happens because of a shortage of blood and oxygen to the heart muscle. It is usually caused by a narrowing or blockage of one or more of the coronary arteries” (What is Ischemia n.d.). Ischemia is a condition that appears when the heart muscle is not getting enough oxygen. A heart attack is also known as “cardiac arrest”. A heart attack can sudden and most of the time is unexpected. According to Tortora, “Cardiac arrest: Cessation of an effective heartbeat, the heart may be completely stopped or in ventricular fibrillation” (p....
