Heart pacemaker

In 1957, an external artificial pacemaker with internal heart electrode is first used. To maintain a patient's heartbeat rhythm an electrode was sewn to the wall of the heart and connected through the chest to an external desk-top pulse generator. A team of scientists at the University of Minnesota, led by Dr C. Walton Lillehei, made this medical advance. However, such bulky equipment was not a good long-term solution since infection often occurred along the electrode wires, and the device required no interruption in the house electricity. So Dr. Lillehei also initiated research on the use of a small portable external pacemaker for these patients with heart block. This ultimately led to the development of the billion-dollar pacemaker industry.
