What makes up an artificial Pacemaker?
An artificial pacemaker is roughly the size of a silver dollar and about as thick as 2 silver dollars together. The pacemaker system is powered by a small battery sealed inside the pulse generator. The battery cannot be recharged. For this reason, the pulse generator must be replaced when the battery’s energy is used up. The pacemaker also includes several electronic circuits. These circuits control the pacemaker’s functions, including the way it monitors your heart’s activity. Replacement of the device usually occurs in 4-8 years.
