Why pacemaker use in heart?

Pacemakers are used to regulate abnormal heart rhythms by delivering electrical impulses to the heart when it fails to beat properly. They are particularly beneficial for conditions like bradycardia, where the heart beats too slowly, or certain forms of heart block. By ensuring a consistent heartbeat, pacemakers help improve blood flow, reduce fatigue, and enhance the overall quality of life for patients. Additionally, they can prevent complications related to irregular heart rhythms.
