PaceMaker Essay -- medical health heart disease

The PaceMakerI. Introduction Heart disease is among the in the maven antecedents of deaths each year. However, many an(prenominal) people with vegetable marrow problems are increasing their longevity with pacemakers. A pacemakers main purpose is to keep the flavour from beating as well as slowly in that locationby preventing the problems associated with slow heart rhythms (passing out, congestive heart failure, and death). sinoatrial nodes are necessary because, while there are many medications that prevent the heart from going too speedy, there are just now a handful that make the heart beat faster. Medications that speed the heart rate are poorly tolerated and often associated with serious side effects. Pacemakers brood with be have intercourse a reliable means of helping people live longer and improve their lifestyles despite having a slow heart rhythm. The eubstances natural pacemaker is a small mass of narrow cells in the top of the right atrium, or chamber, of the heart. It produces the galvanising impulses that cause a heart to beat. A chamber of the heart contracts when an electrical impulse or signal moves across it. For a heart to beat properly, the signal essential travel down a specific path to reach the ventricles. instinctive pacemakers may be defective, causing the heart to beat too fast, too slowly, or irregularly. There may also be a occlusive of the hearts electrical pathways. A pacemaker is a radical to these problems. II. Technical Description Patients require pacemakers for many diametrical reasons. Most pacemakers are implanted to prevent the heart from beating too slowly0. Often, this slowness occurs because there is no cell in the heart that will beat fast enough to maintain proper function, or because there is a shove somewhere in the electrical pathway which does not allow the electrical activity to spread to all of the necessary portions of the heart muscle. The underlying cause of this mi shap may be scar tissue, most frequently from foregoing heart attacks. Sometimes it is simply caused by aging of the conduction system. Pacemakers come in different shapes and sizes. All of them are small and lightweight. Depending on the patient ofs heart condition, the physician will prescribe the number of domiciliate to be paced and a specific kind of pacing. A single-chamber pacemaker paces both the right atrium or the right ventricle with one lead. Single lead pacemakers are used pri... ...ach manufacturer programs this function in a different but characteristic way. A certain magnet rate indicates the indigence for elective or immediate replacement for each model. Although pacemakers are multipurpose life-extending devices, they are not foolproof. Many precautions must be taken for patients with pacemakers, including onslaught maintenance, avoiding microwaves, arc welding (which can create a high-energy field of view that can reprogram pacemakers), power-g enerating equipment, powerful magnets, and cellular phones.
