A pacemaker is a sophisticated electronic device which can monitor the heart’s rate (how fast it beats) and rhythm (the pattern in which it beats), and provides electrical stimulation when there is any abnormality of the rate or rhythm of the heart (it does not beat or beats too slowly or beats irregularly).

A pacemaker is inserted for many reasons, but the two common causes include bradycardia and heart block.
In both these situations the heart might not pump enough blood to meet the body’s needs. Significant decrease in heart rate may affect blood flow to the brain, causing light headedness and (sometimes) fainting.
