A pacemaker is a device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias, which involve the heart beating irregularly.

Heart is the engine of the body . At rest a heart beats up 60- 80 beats/minute .

If the heart beats consistently less than 60 bpm this is referred to as bradycardia. The slowed heart rate does not permit enough oxygen to circulate through the body which can result in dizziness and fainting.

Pacemakers are adjustable artificial electrical pulse generators that can be temporary or permanent.

Pacemaker is implanted through a incision below the collar bone (shoulder) and connect it to the heart through electrical leads , through the leads the pacemaker can monitor heart heartbeat.
