As the lead surgeon and the sole decision maker for all transplant cases‚ I have a dilemma on my hands. I had just received a call and was notified that a heart has become available for a transplant. I currently have 3 patients that are candidates for this heart. Time is of the essence; therefore I have decided to give the heart to Jerry‚ a 55 year old‚ married and father of 3 children. I believe Jerry is the best candidate for the transplant because of his overall situation. As I mentioned before

TYPES OF PACEMAKERS The classification of pacemakers into different types is based on the mode of application of the stimulating pulses to the heart. EXTERNAL PACEMAKERS: These are used when the heart block presents itself as an emergency and when it is expected to be present for a short time i.e during critical post operative periods and in patients during cardiac surgery‚ involving the valves or septum. * The pacemaker is placed outside the body. It may be in the form of wrist watch or in

Living with a Pacemaker or Implantable Cardioverter Defibrillator (ICD) With advances in technology‚ pacemakers and ICDs generally last five to seven years or longer (depending on usage and the type of device) and‚ in most cases‚ allow a person to lead a normal life. In addition‚ advances in device circuitry and insulation have reduced the interference risk from machinery‚ such as microwaves‚ which‚ in the past‚ may have altered or otherwise affected these surgically implanted cardiac devices.

Discuss the influence of endogenous pacemaker and exogenous zeitgebers on one or more biological rhythms (24 Marks) Introduction This essay will outline and evaluate the role that endogenous pacemakers (ep’s) or internal clocks have on our biological cycles. It will also consider exogenous zeitgebers (ez’s) or external timekeepers. The two cycles to be considered are circadian and ultradian. AO1 Psychologists believe that the circadian rhythm (sleep/wake) is controlled by an

Pacemaker The human heart is an essential organ of the human body. Its sole purpose is to supply the body with oxygen by pumping blood through a complex system of veins and arteries. However‚ it is often common for the human heart to suffer from various heart conditions‚ such as a heart block‚ slow heart beat‚ heart attack or heart failure. Such heart conditions can lead to weakness‚ fainting‚ shortness of breath‚ or even possibly death. These can usually be treated with medication but in cases

Essay ON PAcemaker A pacemaker (or artificial pacemaker‚ is a medical device that uses electrical impulses‚ delivered by electrodes contacting the heart muscles‚ to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequateheart rate‚ either because the heart’s native pacemaker is not fast enough‚ or there is a block in the heart’s electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing

Legal Ethics from Deontological‚ Utilitarian and Casuistry Perspectives | | | | | | Deontological ethics are concerned with the intent of an action without regard to the outcome‚ while utilitarian ethics are concerned only with the consequences of the action. Some argue that the legal code of ethics is derived from a utilitarian theory‚ while others argue that it is derived from deontological theory. As deontological ethics are the polar opposite of utilitarian ethics‚ it should

CHAPTER 1 Basic principles of pacing Malcolm Kirk The aim of this chapter is to give sufficient background and information about cardiac pacemakers to allow interpretation of electrocardiograms (ECGs) and telemetry strips of normal pacemaker behavior. For more in-depth information‚ such as would be necessary for programming pacemakers‚ a standard pacing text should be consulted. Several of these are listed in the bibliography. Most italicized terms are defined in the glossary at the end of the chapter

references. References and resources used: Review date: Pacemaker Implantation‚ Adult Pacemaker implantation is a procedure to place a pacemaker inside your chest. A pacemaker is a small computer that sends electrical signals to the heart and helps your heart beat normally. A pacemaker also stores information about your heart rhythms. You may need pacemaker implantation if you: • Have a slow heartbeat (bradycardia). • Faint (syncope).

The largest issue in the case of the pacemaker is whether it is right or wrong to make‚ of course‚ but in order to find our moral correctness compass we must define what Utilitarianism is and from whose standpoint we are looking at this issue. John Stuart Mill‚ who studied under Jeremy Bentham (the father of Utilitarianism)‚ defined Utilitarianism as “actions are right to the degree that they tend to promote the greatest good for the greatest number (Kay 1997‚ p.7).” Racking and stacking the positives
