A pacemaker is a device that helps to regulate the heart beat. Most individuals who need this device are older or are suffering from a particular heart condition. It helps to understand how the heart works and where the pacemaker fits into the entire scheme of things.
The heart is regulated through different electrical pulses. Naturally, the heart is regulated through electrical pulses that travel from the top of the heart to the bottom. This succession of pulses creates enough pressure to move oxygenated blood through the heart.
At times the heart slows or is irregular. It is at this point that getting a pacemaker is imperative. Individuals who have this problem usually experience dizziness, momentary blackouts and fainting spells. Some of the more urgent and serious symptoms include severe chest pain and blurred vision.
Usually, meeting with a heart specialist who has had experience in dealing with these matters is the best way to handle such a situation. He will be able to determine exactly what type of pacemaker that you will require. Choosing the correct pacemaker will ensure that your heartbeat gets back on track.
Pacemakers usually have two components: a generator and a lead. A generator is usually connected to battery as it creates an electrical current that regulates the pulse of the heart. Leads carry the pulse from the generator to the heart in order to stimulate the muscle.
There are three kinds of pacemakers: single chamber pacemakers, dual chambers, and rate responsive pacemakers. Each one serves a different purpose in the context of how they help the heart restore a natural heart beat. The single chamber pacemaker applies electrical current either to the top or the bottom of the heart, depending on which part of the heart needs the most attention. Dual chamber pacemakers apply electrical currents to both areas of the heart, stimulating the entire thing. The rate-responsive pacemaker applies electrical currents depending up the rate of the heart. Sensors can detect whether or not the heart's beat rate needs to be increased, or needs to be reduced, and then applies stimulation accordingly.
The unfortunate thing about pacemakers is that the device is only as good as the manufacturer has made it. Medtronic, one of the leading makers of heart pacemakers, has had a history of making devices that malfunction at the most inopportune time. So people have died as a result.
