Chapter 3 Exercise 12 PROCEDURE NOTE Hagler‚ Jason 7935409 Jennifer Hutto‚ MD December 26‚ 2012 DUAL CHAMBER CARDIAC PACEMAKER INDICATION Protracted‚ high degree‚ atrial ventricular block‚ postinferior MI‚ and aortocoronary bypass grafting. DESCRIPTION The patient was brought to the heart cath lab. Left infraclavicular area was prepared and draped in the usual sterile fashion. Local anesthesia was achieved with 1% plain Xylocaine. Femoral vein was punctured with an 18-guage needle

In the qualitative study‚ Cardiovascular Patients’ Experience of Living with Pacemaker: Qualitative Study‚ the objective was to look into the experiences of patients living with a pacemaker. In the introduction‚ the authors describe the reason of cardiovascular disease being one of the most common causes of disease associated mortality being that there is an increase in urbanization‚ industrialized lifestyle and decrease physical activity as well as socio-economic conditions. Coronary artery disease

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

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

great stunts‚ you’ll be on the edge of your seat. Damon plays the role of Jason Bourne a man found‚ floating in the sea‚ by a sea vessel suffering from amnesia and bullet wounds. The only clue of his true identity is a small laser which projects someone’s bank details. In the Bourne Identity‚ most of the stunts are close combat. Unlike many other films‚ such as James bond and Mission Impossible 3‚ the weapons used by Jason Bourne are objects lying around him at the time and his excellent and mysterious

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

Materials Used In Pacemakers Image result for what is a pacemakerThe way how a pacemaker is constructed is very crucial to how it would function later. The materials used to construct pacemakers must be non-toxic‚ sterilisable and able to function in the environmental conditions of the body. Some of the fundamental parts of the pacemaker such as the casing‚ battery‚ circuitry and the leads are all made with biocompatible materials or non-toxic materials. Usually‚ the casing along with the lead is

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
