Our pacemaker‚ like many‚ is disrupted by waves emitted by many other devices. This makes it so that people with pacemakers cannot use certain electronic devices such as cellular phones and MP3 players. Patients with implanted pacemakers are also unable to receive MRI’s and go through metal detectors‚ as these also interfere. The pacemaker‚ can greatly affect the patient’s working life‚ as arc welders emit waves that inhibit the pacemaker. Patients are also advised from lifting heavy loads and playing

Wall The heart is composed of cardiac muscle which enable the heart to contract and allow the synchronization of the heart beat. The heart wall is divided into three layers: the epicardium‚ myocardium‚ and endocardium. * Epicardium - outer protective layer of the heart. * Myocardium - muscular middle layer wall of the heart. * Endocardium - inner layer of the heart that is continuous with the inner lining of blood * Cardiac Conduction * Cardiac conduction is the rate at which

Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

A cardiac physiologist’s role comprises of recording and analysing a variety of physiological data required to assist in the diagnosis and treatment of different cardiac diseases (Scst.org.uk‚ 2016).

In addition‚ cardiac physiologists are also trained to assist in cardiac catheterization

have some input on the memo about patients with pacemakers and the new pacemaker technology out today that I would like to share. I have done a lot of research about this new pacemaker and I do feel that it is safe to use with an MRI‚ but with limitations. A pacemaker is a surgically implanted medical device that is installed to generate electrical impulses to treat irregular or stalled heart beats. If you were to put a patient with the old pacemaker in an MRI‚ there is a good chance the magnetic

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

Summary: AED Defibrillators: Having access to an AED is essential for resuscitating those who have suffered from SCA (sudden cardiac arrest). Because the incidences of SCA are increased during and after strenuous physical activity‚ every school should have AED(s) that can be accessed very quickly. Sudden Cardiac Arrest: Sudden cardiac arrest is the leading cause of death in young athletes.
