As we call it by the name pace maker let us just why it is defined so … defining it… A pacemaker is a small electrical device that runs on a battery and produces low voltage rhythmic electrical signals that keep the heart beating when the heart's own electrical signals are deficient basically in a more simple way A pacemaker continuously "watches" the electrical system of heart and provides the needed electrical signal if the heart does not do so. During periods when the heart produces its own electrical signal normally, the pacemaker does nothing except to continue to monitor. So as it has to be placed within the body it has to be biocompatible, let me come to its biocompatibility a bit later before that lets see the basic part of the pacemaker .
A pacemaker system is made up of three main parts:
- · The generator, a smooth, lightweight case containing a tiny computer and a battery which makes the electrical signals needed to pace the heart;
- · The connector or header, which is the part of the generator where the leads are attached
- · The leads, which are wires covered in soft, flexible plastic that are inserted into the heart to help the generator watch the heart and carry the generator’s signals to the heart.
Implanting the pacemaker
Toto implant the pacemaker there is a simple surgical procedure performed in the operating room or in the cardiac catheterization lab. When the decision to implant a pacemaker is made some prior instruction need to be followed
- · Do not have anything to eat or drink for 6 hours before your procedure.
- · If you are a diabetic you may be instructed to reduce or not take your insulin or other diabetic medicine on the day of the procedure to avoid low blood sugar.
- You may be asked stop taking aspirin or other blood thinners several days prior to the procedure to avoid unnecessary bleeding
· Blood tests may be required on the day of the procedure or before it.
· Usually you will be asked to arrive in the hospital on the morning of the procedure several hours before the procedure so that you can be adequately prepared to undergo the surgery. After the procedure usual hospital stay is one day.
