¶ … Heart
The basic work of the heart is to pump blood to the entire body. It performs two types of functions, electrical and mechanical. The electrical function of the heart is the periodic contraction that is triggered by the pacemaker. The pacemaker generates the pumping effect throughout the heart. This pumping action commonly known as action potential is carried in an electrical conduction system. The mechanical function is the fluidic movement of blood; the heart is a pump. The heart's anatomical features include; ventricle, which is the pump, heart valves; that allow blood to flow one way and the atria, which includes the four chambers of the heart. The heart is susceptible to disease and as a result if unable to pump blood can lead to failure in other body organs.
Treated Heart Conditions
Cardiology is generally a field of medicine focusing on diagnosis and treatment of the heart. Discussed here are some conditions of the heart, there causes and symptoms. According to Marill (2012), Ventricular fibrillation occurs when the heart's electrical impulses are unsynchronized. When this happens, the right and left ventricles unusually contract fast disabling them from pumping enough blood to the body. This condition may occur without notice and when it does, thorough medical tests are recommended to get a clear prospective of the disease. Marill explains that Angina pectoris and myocardial infarction result from build up of plaque around the coronary artery leading to clogging and narrowing of the walls. The narrowing deprives the myocardium of oxygen and necessary nutrients. In some instances, heart defects and other infections can affect the pacemaker node; this can result to irregular and slow heart rhythm: a condition known as bradycardia. Symptoms...
Aneurysms of the aorta is the swelling of the heart's aorta twice the normal size on the side. This happens due to weakening of the walls or because of other medical conditions such as atherosclerosis. However, this may bring about internal bleeding and an excruciating pain to the patient; if not urgently treated, sudden death may occur.
Common Heart Procedures
Cardiologists perform diagnostic and curative procedures in assisting patients with heart conditions. According to Heartmart (2007), cardiologists use catheterization to diagnose heart conditions; this procedure determines the heart's pressure. They can also determine clogging in the arteries by injecting dye, a procedure also known as coronary angiography. This procedure can be performed alongside coronary angioplasty. Once the condition has been identified, there are various procedures at the cardiologists' disposal to manage them.
Coronary artery bypass is a commonly used procedure to treat heart failure or attack caused by narrowing of the artery. Here the abnormal artery is replaced by another from the body. "Off-pump coronary artery bypass grafting" (Puskas, et al., 2003), is an improvent of the former, it assures total revascularization and limited myocardial injury. Angiopasty is another common technique applied in instances where the patient's arteries are clogged with plaque. It is the non-surgical option of treating the narrowing of heart arteries. Heart transplant is another procedure and is the most involving surgical procedure. According to Fishbein (2012), there are 4,000 people in the United States of America (USA) who need heart transplant, unfortunately only half of them can benefit from the available donor hearts.…

Wood indicates that "everyone has different motivations and aspirations that they wish to achieve in their life. Work-life balance is about adjustments that can be made to working patterns to enable people to combine work with the other facets of their life. Bratton and Gold (2003: 105) de-ne work-life balance as, 'the relationship between the institutional and cultural times and spaces of work and non-work in societies where income
Components of a PERIODIC HEALTH Examination A periodic health examination is an evaluation of the body and its functions using inspection, palpation, percussion, and auscultation. A complete health assessment includes information about ones medical history and lifestyle, laboratory tests, and disease screening. A periodic health examination can help identify health problems at an early stage when they are easier to control or cure (Laine). Another benefit of these visits is that
Psychology -- Counseling -- Bowen Family Therapy Bowen Family Therapy is a system-based treatment. Rather than treating the individual as a completely separate person, Bowen places the person in the context of his/her family. By examining at least three generations of an index person's family, the therapist can develop a strong understanding of the factors that formed and still influence the patient/client. In addition, the system-based intervention for treating an issue
Buddhism -- the Heart Attack Sutra The Craziness of the Heart Sutra Before specifically referring to Chapter 1, one should note that the difficulty of a Western mind readily understanding the tenets and nuances of Buddhist thought are made abundantly clear in reading Brunnholzl's book. Epstein points out just such a problem when he explores the difficulty of translating Buddhist philosophy to workable 21st Century psychotherapy, for several reasons: differences in languages
Congestive Heart Failure It is a fact that Congestive Heart Failure is an extremely frightening word and an equally frightening concept to comprehend, and when a loved one, or oneself has been diagnosed with this condition, it is quite natural to relapse into a state of depression or panic. However, it is not an untreatable disease, and with the correct and appropriate treatment methods, and with the right physician attending, the
Worries of the Heart How does the concept of gender change the way we think about colonialism in Kenya and Africa? Give specific examples. Is colonialism 'bad' or 'good?' Conventional wisdom in the 19th century suggested that colonialism was beneficial to the residents of Africa and East Asia, because it was 'civilizing' and was even necessary, to 'carry the white man's burden' of enlightening non-Christians. Then, in the wake of the decolonization
