Artificial Pacemaker:


Cardiac pacemakers are generally used to manage a slow or irregular heart rate. The pacemaker system applies precisely timed electrical signals to induce heart muscle contraction and cause the heart to beat in a manner very similar to a naturally occurring heart rhythm. A pacemaker consists of a pulse generator, at least one electrode, and one or two pacing leads connecting the pacemaker to the heart.The casing of the pulse generator functions as housing for the battery and circuits,which provide power.


It is usually implanted between the skin and pectoral muscle. The sealed lithium iodine battery provides electrical energy to the pacemaker. This battery replaced the mercury-zinc battery in 1975, extending the life of some pacemaker models by over 10 yr.The circuitry converts the electrical energy to small electrical signals.
