Implantable cardiac pacemaker - Essay Example Its blood pumping role is set at a certain pulse limit below or above which the process becomes abnormal which may be fatal.In this regard, a device called pacemaker which is an artificial pulse regulator was invented for those with malfunctioning heart muscle. It is the comparison between the structure and functions of the device that is taken through critical investigation with the aim of establishing its mechanism of pulsating. The clinical problem that the device addresses, including a brief description of the therapeutic function, and a brief history of the development and deployment of the device The management and caring for patients diagnosed with cardiac problem has been very challenging in the present world owing to the complexity of these infections. Electric pacing is one of the latest medical engineering developments that has gained acceptance as being one of the common prophylactic or therapeutic strategies of managing cardiac problems in patients. In the management of myocardial infections compounded by system injury, temporary cardiac pacing devices often play a significant role (Luderitz, 2012). It is at this point that cardiac pacemaker is deployed in order to help patients suffering from cardiac problems. The primary function of cardiac pacemaker in clinical and medical health is to pace hearts to help in recognizing the presence of intrinsic cardiac electrical activity and to restrain pacing of the heart in the absence of normal intrinsic impulses. This electric pacing device is often implanted in the heart of patients diagnosed with sinus node dysfunction. Only two approaches were commonly employed in the restoration of cardiac arrest (Bernstein, 2002, pp.260-2). This happened years before cardiac pacemakers were advanced. The two methods were intracardial therapy and mechanical simulation. The first successful heart pacing treatment was a case of an Australian baby that used Lidwill’s apparatus as the artificial pacemaker. Irrespect ive of the drugs and medical therapy used in this first pacing case, medical doctors at the New York Beth Hospital attributed the success to the prick needle inserted into the heart. The design was named after the founder, Hyman’s pacemaker, which took place in 1932. Interest in pacemakers (artificial pacemakers) with respect to cardiology rekindled after WWII, this time round, the exercise was spearheaded by Callagan, Hopps, and Bigelow, research experts at the University of Toronto, Canada. After conducting a thoracotomy, John Hopps designed the first artificial pacemaker with the ability to produce impulses at the desired rhythm (Bigelow, 2008, p.841). However, the first case of clinical application of pacemaker happened in 1952. This first successful application of pacemaker involved Zoll’s pacemaker. This occurred at the Boston Beth Israel Hospital when a man aged 75 was admitted to suffering episodes perceived to be Stokes Adams attack (collapse without warning a nd unconsciousness) and heart blockage, a condition that is common among the elderly and is associated with ischemic disease of the heart (Bigelow, 2008, p. 842). The first implantation of the pacemaker took place on October 8, 1958. This involved Mr. Larsson Arne (aged 43) who was found to be suffering from Stokes-Adams attacks and complete heart block. However, following the increase in technological innovation and advancements in the late 1970’

Cause and Effect;What would be the effects of dropping out of high Essay

Cause and Effect;What would be the effects of dropping out of high school - Essay Example High school dropouts will hardly provide any meaningful skills to the job market and therefore, not able to secure good jobs. This causes a sharp drop in living standards among high school dropouts. Lack of education means lack of skills needed by most employers if not all. This leaves high school dropouts with no choice than to do the unskilled jobs that are lowly paid. Whereas this is a loss to the employment sector, most of the loss occurs to the dropouts since they forego the gratification that comes with professional jobs. Such dropouts can hardly support their families with the little income they have. More notably, they are most likely to create a poor generation since their family foundations are already economically unstable. With the increasing problems associated with global economic crisis, high school dropouts are most likely to face overwhelming competition and difficult living conditions. US government has to make a huge budgetary allocation every year in aid for the poor families that cannot support themselves. A great number of high school dropouts add to this burden every year. This is because as they can hardly support themselves economically. Additionally, they nurture families that are not economically stable thereby adding more pressure to the already heavily burdened government spending. For instance, the government has to struggle raising funds to support a healthcare program for the poor even when the poor, such as high school dropouts, cannot afford to contribute financially to the program. Poor living conditions and lack of livelihood is a prerequisite to criminal activities. Criminal activities are most likely to be more prevalent among high school dropouts due to inability to generate enough income. High school dropouts hardly have any option apart from engaging in criminal activities due to the overwhelming competition in the modern society. More notably, high school dropouts are, most certainly, likely to associate with
