- Permanent Pacemaker implanation Animation (2).

Permanent Pacemaker implanation Animation.  

 The heart is located in the center of the chest, enclosed by the breast bone and rib cage. By contracting in a rhythmic way, it causes the blood in your body to circulate.

 A normally functioning heart beats at a rate of between 60 and 100 contractions per minute. These contractions are triggered by a small piece of heart tissue called the SA node. The SA node generates a small electrical signal that is transmitted by nerves to the surrounding muscle. These electrical impulses are what cause the heart muscle to contract.

In some people, the SA node fails to cause the heart to contract with its normal rhythm, causing an abnormal heartbeat or arrhythmia. The most common form of arrhythmia, for which pacemaker surgery is often recommended, is bradyarrythymia - or slow heart rate.

A pacemaker is a device that is designed to provide an electrical signal to the heart muscle and to help it maintain a proper rhythm.

Pacemaker will consist of two major pieces . . . a small metal box that contains a battery and other electronic components and an insulated wire, called a lead, which will carry the electrical impulses from the pacemaker to the heart.

Pacemaker will be permanently implanted in  chest and, depending on your condition, either one or two leads will be attached to the heart muscle.
