Book Description
Today hundreds of thousands of Americans carry pacemakers and implantable cardioverter-defibrillators (ICDs) within their bodies. These battery-powered machines—small computers, in fact—deliver electricity to the heart to correct dangerous disorders of the heartbeat. But few doctors, patients, or scholars know the history of these devices or how "heart-rhythm management" evolved into a multi-billion-dollar manufacturing and service industry. Machines in Our Hearts tells the story of these two implantable medical devices. Kirk Jeffrey, a historian of science and technology, traces the development of knowledge about the human heartbeat and follows surgeons, cardiologists, and engineers as they invent and test a variety of electronic devices. Numerous small manufacturing firms jumped into pacemaker production but eventually fell by the wayside, leaving only three American companies in the business today. Jeffrey profiles pioneering heart surgeons, inventors from the realms of engineering and medical research, and business leaders who built heart-rhythm management into an industry with thousands of employees and annual revenues in the hundreds of millions. As Jeffrey shows, the pacemaker (first implanted in 1958) and the ICD (1980) embody a paradox of high-tech health care: these technologies are effective and reliable but add billions to the nation's medical bill because of the huge growth in the number of patients who depend on implanted devices to manage their heartbeats.

Book Description
Wilson Greatbatch, an electrical engineer in Buffalo, NY, had a brilliant idea and the technical know-how to turn his idea into a practical device, for which millions of people today are grateful. This is the story of the first pacemaker by the man who invented it. Intrigued by electronics from the time he was a boy, Greatbatch earned a degree in electrical engineering from Cornell University. It was during his time at Cornell that he first became interested in the medical applications of electronic devices. He learned about the problem of heart blocking at Cornell and knew it was fixable in principle, but at the time the vacuum-tube technology was impractical for medical use. By the 1950s he was teaching at the University of Buffalo School of Electrical Engineering and the first silicon transistors had just been invented. While using one of the new $90 transistors on another project Greatbatch discovered by accident, as he describes it, the proper design for a blocking oscillator that he immediately knew would work as a pacemaker. He soon interested Dr. William Chardack, chief of surgery at the Veteran''s Administration Hospital in Buffalo, in the project, and by 1958 they were conducting animal experiments. Greatbatch quit his job and for the next two years devoted full-time in his wood-heated barn workshop to building one pacemaker after another. During this time he built fifty pacemakers, forty of which went into animal experiments. By 1960 he and a team of surgeons and engineers had gained enough knowledge from the trial and error of the animal experiments to feel ready to begin implanting the remaining ten devices in people. The first trials went well and Greatbatch''s device extended the lives of many of these seriously ill patients by decades. What followed were years of hard work refining the battery and electrode technology, marketing the pacemaker to an initially skeptical medical community, and keeping the company that manufactured the device profitable. Reminiscent of Edison''s many dogged attempts to find the right solution in pursuit of an ingenious idea, The Making of the Pacemaker is a human-interest story at its best and also an important firsthand account for the medical archives of an invention that today saves millions of lives.

Book Description
After more than a decade of successful application of cardiac pace makers in the therapy of cardiac rhythm disorders, technological and clinical experience has reached a level, at which a technical survey of this field should be of general interest and might promote the further improvement of pace maker therapy. The papers contained in this book were presented at the International Symposium on Advances in Pacemaker Technology, held at Erlangen on Sep tember 26 and 27,1974 under the auspices of the Societas Physica Medica Erlangensis. One of the traditional aims of the Societas has been the advance ment of diagnosis and therapy by the adaptation of medical skill to modern technology and scientific engineering conceptions. The major objective of this book is to present, in expanded form, the lectures given by internationally known basic and clinical researchers in the field of artificial pacing of the heart and to make that information available to a wider public. The experience discussed covers the principles and main methods of pacing using implantable and external, fixed rate, R-wave or P-wave triggered pacemakers with electrodes placed in the myocardium either surgically or transvenously, and powered by zinc-mercury oxide or rechargeable batteries. Particular emphasis was put on problems of pressing importance at the present time, such as the increase of pacemaker longevity with lithium iodide and nuclear-powered batteries or improved electrodes, as well as the postoperative management of a steadily increasing number of pacemaker patients.
