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.

To really understand why people even need pacemakers in the first place, you have to understand how the human heart works. Your heart keeps blood pumping throughout your body, and every heartbeat sends electrical signals to do this. If these signals become weak or stop altogether, it could be serious or even fatal.

If a doctor recommends pacemakers, it is likely due to an abnormal heartbeat, referred to as an arrhythmia in medical terms. The unsteady beat could cause less blood flow and even organ failure if it is really serious and goes untreated. Most patients suffer from dizzy spells, fainting, and even chronic fatigue that makes it hard to live a normal life.

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.

The doctor may also prescribe a stress test, which records heart rate while it is active. If you are well enough, you will have to exercise on a treadmill to get it pumping. If not, a medicine can be administered to give your heart a similar, elevated beat.

The surgery required should the tests prove you need the device is in two parts. The first puts wires into your heart tissue, and requires an incision near the shoulder. The second incision is where the box and battery goes, near the chest area. The wires are connected to the box to make a complete circuit to help regulate the heartbeat.

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.

Another thing to look out for is anything with a magnetic field or electrical devices, as they could interfere with the operation of your new device. This includes cell phones, so try to use speakerphone when you can and do not put it in your shirt pocket or near where the device is implanted in order to stave off any adverse effects. Just remember to do what your doctor tells you and you are on your way to a better life.
