What is an Artificial Pacemaker?
An Artificial Pacemaker is an electronic medical device installed in the heart that supplements the human body's natural pacemaker. When it detects abnormalities in the rhythm of the natural pacemaker with which all humans are born, the artificial pacemaker sends an electric stimulus to the heart, thereby returning its rhythm to normal.
How Pacemakers Work
St. Jude Medical's Pacemaker System is a highly precise system comprising a pulse generator and a lead for sending electric stimulus to the heart. The system is manufactured using the highest quality materials and components. Thorough testing of external casings and internal functions are conducted on every unit produced. St. Jude Medical tests every component and finished product at each manufacturing stage. Attention is paid to the most minute details in the manufacture of each pacemaker. This process is similar to that used in the manufacturing of manned space vehicles.
How Long do Pacemakers Last?
Pacemakers use solid state-lithium-iodine batteries as their power source. These batteries will be gradually depleted over a long period of use. However, your St. Jude Medical's pacemaker is configured to detect the need for battery replacement long before battery life is completely exhausted. Therefore, as long as you undergo regular hospital checkups, your pacemaker will ensure your safety.
