Artificial pacemaker

A device used for generating electrical signals and maintaining regular heart rhythm in patients suffering from a disturbance in electricity generation or transfer in the heart.

The need for an artificial pacemaker can be temporary and transient or chronic and permanent.

There are external pacemakers (the pulse generation takes place outside the chest), which are usually used for pre-hospitalization period.

In permanent pacemakers, the battery is implanted subcutaneously and the electrodes are implanted into the heart.
