PDF-(EBOOK)-Machines in Our Hearts: The Cardiac Pacemaker, the Implantable Defibrillator,

Today hundreds of thousands of Americans carry pacemakers and implantable cardioverterdefibrillators ICDs within their bodies These batterypowered machinessmall computers in factdeliver 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 heartrhythm management evolved into a multibilliondollar manufacturing and service industryMachines 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 heartrhythm 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 hightech health care these technologies are effective and reliable but add billions to the nations medical bill because of the huge growth in the number of patients who depend on implanted devices to manage their heartbeats.
