Pacemakers have been around for decades, but there are still many misconceptions about how they work, what they do and who needs them. Millions of people around the world who have pacemakers, but it is something that rarely is.

gesprochenDie people get a pacemaker, a problem correct known with the heart as a heart arrhythmia. layman’s terms, this means the heart’s natural rhythm is always out-of-whack.

While just about every well but occasionally experience short bouts of out-of-rhythm of cardiac activity, have cause some people stubbornly arrhythmias, symptoms, ability to affect a normal life, and are largely unpredictable. These people need a pacemaker. symptoms that require you mean a pacemaker include fatigue, dizziness, drowsiness, and fainting and inability to not rely too out of breath exercise.

These are pretty vague symptoms and a person have easy access to all these conditions and need a pacemaker. But let’s talk about what’s really going on.

The healthy heart beats in a certain pattern, which the upper chambers of the heart (atria) and lower chamber (ventricle) coordinates in a way that the heart beat very efficient in converting a very large amount of blood through is the body. This blood is called the cardiac output. If cardiac output falls to zero, the person dies in a matter of minutes.

But in many cases, starts the electrical system of the heart (not the pump power) shaken . This is an electrical problem of heartnot heart out of the inability to efficiently pump blood. But many people do not realize the heart as an electrical system.

generates electrical impulses through the heart lead in heart rhythm. If the heart ceases to generate electricity in a regular way, or the current no longer travels right through the heart muscle may be the result of an arrhythmia.

There are two main types of heart rhythm disturbances that can cause a person’s always a pacemaker is. The first “Sinus Node Dysfunction,” which sounds very complicated. In reality it means that the heart no longer produces electrical energy at the right speed.

The heart has the amazing ability to electricity to produce. This is a small area of ​​the tissue reached the so-called sinus node (nicknamed “sinus node” or simply “sine”) in the upper right side of the heart. If the sinus node slowly or produces electricity or irregular electricity produced fine at low prices but not compete, if you and practice need a faster heart beat … that is sinus node dysfunction.

About half of all people with pacemakers have this condition. The resulting arrhythmia for a person with sinus node dysfunction is a heart rate to slow is to support normal activity. The medical term for this is “sinus bradycardia.” Because you do not have enough cardiac output to normal things, you can always awkward, tired, dizzy or even loss of consciousness do things you used to do.

The second type of heart rhythm disturbances that can cause a heart pacemaker sounds much easier, but the name is a little misleading. It’s called “block-to-heart.” heart block is not really a blockade at all. Rather, it means that the electrical impulses through the heart no longer sufficiently efficient journey through the heart muscle. The electrical energy is delayed or even blocked in some areas.

In a healthy heart, electrical energy, which causes the heart begins in sinus node (top, right side of the heart) is lost. It then travels through the atrium and then down. As it makes its way to the chambers, passes it through an intersection called “AV node or AV node.

Once the electrical energy passes through the AV node, it travels to the ventricles and causes the ventricles to contract and pump blood. heart block occurs when there is a problem in the AV node. Sometimes Electrical energy is delayed in a way that the atria and ventricles are no longer working together.

In extreme forms of AV block, the energy from the upper half of the heart can not be gone into the lower half at all (this is called “complete heart block”) is impaired, since the atria and ventricles do not work in harmony, cardiac output, this can result in the same list of symptoms:.. light-headedness, dizziness, shortness of breath, tiredness all the time, and even fainting

. About half of all people need pacemakers have some form of heart block (it can be mild to severe).

heart rhythm disturbances can be quite complicated. For example, a person both types of heart rhythm disturbances, that is this a heart pacemaker that could demand can have a person in sinus node dysfunction and heart block simultaneously. Even those who only arrhythmia now, perhaps, a different type of heart rhythm disturbances in the future to develop.

pacemaker can do this by “filling in the missing shots.”

pacemaker small electrical devices are implanted in the chest. They supply electric energy to the heart at precisely the right moment to keep what matter is in such a way as “normal” as possible. restore many patients pacemaker normal heart rhythm. In some patients, the arrhythmia are strictly made for a normal heart rhythm again, but the pacemaker can at least come close.
“know”
pacemaker when electrical energy to supply to the heart because they control every heartbeat and depending on how to respond, the physician programs on it. This is a useful function, because many patients do not require pacemaker constant stimulation. In fact, for many people, heart rhythm disturbances did not permanently come, but come and go, sometimes for a short time. The pacemaker monitors the heart activity and jumps in with stimulating (stimulating) energy when an arrhythmia occurs.

There is currently no cure for arrhythmias in the sense that an erratic heart rhythm can not be restored with an operation or a pill to help. True, surgery, pills and other means to manage symptoms or even real part of the problem.

pacemakers are actually very safe ways of dealing with certain arrhythmias. Although they are implanted in the body, do not supply them drugs or other chemicals in the body. They use electricity, which would create the substance of the body itself, is if they could.

doctors great flexibility in terms of how the pacemaker is programmed so that they are suitable for a wide range of people, from newborn to the bedridden elderly athletes.

and pacemakers have a memory so that they return to the doctor, what was in the patient’s heart los report. Not everyone can arrhythmias be treated with a pacemaker. But for cardiac arrhythmias such as AV block or sinus bradycardia, heart pacemaker a safe, effective and proven technology that can make a big difference in the lives of those who need them.
