ABSTRACT: John Hopps was born in Winnipeg in 1919 and made many contributions to the field of medicine before his death in 1998. His early work in biomedical engineering eventually led to the development of the implantable cardiac pacemaker, a device that now keeps hearts beating around the world.

Where is the pacemaker from?

Your heart's sinus node is your natural pacemaker (found in the upper right chamber of the heart, known as the atrium). It sends an electrical impulse to make your heart beat. The job of a pacemaker is to artificially take over the role of your sinus node if it's not working properly.

What are pacemakers made from?

An article in the U.S. National Institutes of Health's National Library of Medicine describes a pacemaker as an implant that is made up of three major components: device pulse generator, device controller-monitor, and leads. The casing for the components is usually made of Titanium, Number 22 on the periodic table.
