PaceMaker Essay -- medical health heart disease

The pace shewrI. Introduction Heart disease is among the leading causes of deaths each year. However, many flock with nerve problems are increasing their longevity with pacers. A pacemakers main purpose is to keep the heart from beating too easy thereby preventing the problems associated with slow heart rhythms (passing out, congestive heart failure, and death). Pacemakers are needed because, while there are many medications that prevent the heart from qualifying too fast, there are only a handful that make the heart beat faster. Medications that speed the heart rate are indisposed tolerated and often associated with serious side effects. Pacemakers have become a received means of helping people live longer and improve their lifestyles disrespect having a slow heart rhythm. The bodys natural pacemaker is a sm in all mass of specialized cells in the top of the castigate atrium, or domiciliate, of the heart. It produces the galvanic impulses that cause a hear t to beat. A chamber of the heart contracts when an electric impulse or signal moves across it. For a heart to beat goodly, the signal must travel down a special path to reach the ventricles. Natural pacemakers may be defective, do the heart to beat too fast, too slowly, or irregularly. There may also be a blockage of the hearts electrical pathways. A pacemaker is a solution to these problems. II. Technical Description Patients rent pacemakers for many different 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 block 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 mishap may be scar tissue, most frequently from previous heart attacks. Sometimes it is barely caused by ag ing of the conduction system. Pacemakers come in different shapes and sizes. solely of them are small and lightweight. Depending on the patients heart condition, the doctor will prescribe the number of chambers to be paced and a specific kind of pacing. A single-chamber pacemaker paces either the remediate atrium or the right ventricle with one lead. Single lead pacemakers are used pri... ...ach shaper programs this function in a different hardly characteristic way. A certain magnet rate indicates the need for elective or warm replacement for each model. Although pacemakers are useful life-extending devices, they are not foolproof. many precautions must be taken for patients with pacemakers, including battery maintenance, avoiding microwaves, arc welding (which provoke create a high-energy field that can reprogram pacemakers), power-generating equipment, powerful magnets, and cellular phones.
