Q. What is the use for pacemaker and hoe does it work?
A. It is used in the case when the normal pacemaker in the heart fails. A very fine wire is connected to the main vein till the tip touches the inside of the heart wall. This wire is further connected to a small battery which discharge an impulse regularly which kindly takes over from the faulty mechanism. If the pacemaker is for temporarily usage, then its battery can be worn outside. But if it is needed permanently, then the battery is implanted under the skin of chest wall.
