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
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
Marc A. Rodwin draws on his own experience as a health lawyer--and his research in health ethics, law, and policy--to reveal how financial conflicts of interest can and do negatively affect the quality of patient care. He shows that the problem has become worse over the last century and provides many actual examples of how doctors' decisions are influenced by financial considerations. We learn how two California physicians, for example, resumed referrals to Pasadena General Hospital only after the hospital started paying $70 per patient (their referrals grew from 14 in one month to 82 in the next). As Rodwin writes, incentives such as this can inhibit a doctor from taking action when a hospital fails to provide proper service, and may also lead to the unnecessary hospitalization of patients. We also learn of a Wyeth-Ayerst Labs promotion in which physicians who started patients on INDERAL (a drug for high blood pressure, angina, and migraines) received 1000 mileage points on American Airlines for each patient (studies show that promotions such as this have a direct effect on a doctor's choice of drug). Rodwin reveals why the medical community has failed to regulate conflicts of interest: peer review has little authority, state licensing boards are usually ignorant of abuses, and the AMA code of ethics has historically been recommended rather than required. He examines what can be learned from the way society has coped with the conflicts of interest of other professionals --lawyers, government officials, and businessmen--all of which are held to higher standards of accountability than doctors. And he recommends that efforts be made to prohibit and regulate certain kinds of activity (such as kickbacks and self-referrals), to monitor and regulate conduct, and to provide penalties for improper conduct. Our failure to face physicians' conflicts of interest has distorted the way medicine is practiced, compromised the loyalty of doctors to patients, and harmed society, the integrity of the medical profession, and patients. For those concerned with the quality of health care or medical ethics, Medicine, Money and Morals is a provocative look into the current health care crisis and a powerful prescription for change.
