How A Pacemaker Saves Lives

By Shirley Stewart


There was a time in the past when heart problems meant that your entire life would change, and you may have severe limitations on your diet and activities. Luckily, with today's stellar medical technology improving all the time, a heart condition does not have to mean impending doom. With a pacemaker, you are able to live a much more normal life.

In order to figure out who might need pacemakers or why, it is important to understand the human heart. It pumps blood through your body to keep you alive, but the way it does so is quite complex, involving a series of electric signals. Problems occur when the signals do not work properly or stop working altogether, which is dangerous.

Pacemakers are usually used to correct an arrhythmia, which is an abnormal heartbeat rate or pace. It could leave to intermittent or even chronic fatigue or fainting, which could take a serious toll on your health. In fact, it could be deadly if left untreated, because it can cause blood flow to slow or stop to the major organs, which results in organ failure.

Any doctor who sees a patient who has the telltale signs of an arrhythmia will have tests run to see if their suspicions are correct. This may mean an EKG, which is quick and painless for the patient, which is why it is so commonly done. The doctor gets a recording of all electrical action in the heart.

An echocardiography, also called an echo for short, involves using waves of sound to record the functions and flow. It also measures the shape and size or everything, including the chambers and valves and makes sure they are working properly.

For patients who are still active and can run on a treadmill, they may ask them to do so with sensors attached, also called a stress test. For those who cannot run because of fatigue, they can drink medicine that increases heart rate for a similar effect.

Once it is decided you do need one, you will go through a surgery that takes a few hours of time. During the surgery, a needle is put into a vein near your shoulder. The wires of the device are strung though and placed on the heart itself. Then a small incision is made in your chest and a small metal box is inserted and connected to the wires.

This procedure requires that you stay overnight for observation and to help stave off infection. You will likely need some over the counter medication to help with a little pain or soreness, and will have to take it easy for at least a month afterwards to let your body fully recover from the surgery.

Once you have the device installed, you should try to avoid prolonged use of electrical devices, or those with a strong magnetic impulse or field. This includes cell phones and microwave ovens, two things most people cannot live without. You can, however, use a cell phone, just use it on the opposite ear from where your device was installed, or use speaker phone.
