Pacemaker
A pacemaker is one of the most significant innovations in the healthcare industry, which is designed to help regulate an abnormal heartbeat. The pacemaker is implanted in the chest and consists of a battery that can last around 8-10 years. This device also comes with a pulse generator that generates electrical impulses to stimulate the heart.
This works in conjunction with the human heart and senses heartbeats. So, in case it senses that your heart has missed a heat or slow heartbeat, it sends a signal at a steady rate to stimulate the heart. At the same time, when the heart works well, the pacemaker does not need to stimulate the heart.
