The primary motivation for successful cardiac pacing paralleled the development of open heart procedures for patients with congenital heart disease. This chapter reviews the history of the cardiac pacemaker and the implantable cardioverter defibrillator....
Pacemaker, electronic cardiac-support device that produces rhythmic electrical impulses that take over the regulation of the heartbeat in patients with certain types of heart disease. A healthy human heart contains its own electrical conducting system ca
More than 50 years have passed since the first permanent cardiac pacemaker was implanted in 1958 by Dr. Senning and colleagues. How much closer are we now to developing a perfect pacemaker device? Multiple difficulties have been overcome, while many others are still to be addressed. Thus, the...
When large-area electrodes are applied to the heart or chest to induce ventricular fibrillation, more current is required and the current spreads to stimulate more sympathetic nerve fibers in the ventricles. 展开 关键词: Cardiac Pacing, Artificial Pacemaker, Artificial Cardiology History, 19th Century...

first patented pacemakerDr Albert Hyman patents the first 'artificial cardiac pacemaker' which stimulates the heart by using a transthoracic needle. His aim was to produce a device that was small enough to fit in a doctor's bag and stimulate the right atrial area of the heart with a suitably...
Like the cardiac pacemaker, one of which we show on the exhibition as well." 伯契纳克:“技术革新对多数人的意义是计算机如今无处不在。当你通过一个路口,可能就有计算机控制着交通灯。但技术革新不仅仅是笔记本或智能手机,它们围绕在我们生活周围,有时候甚至深入我们体内,例如我们展览中也有展示的心脏起搏器...
Clinical symptoms of pacemaker malfunction are variable and include syncope, dizziness, palpitations, and slow or fast heart rate. Extracardiac stimulation or hiccup may be present. Obtain as much information as possible regarding the pulse generator, leads, and programmed values. Information on time ...
Patrick is a 70-year-old diabetic man with a 2-year history of stable chest pain when he exerts himself. He is awoken from sleep with the acute onset of crushing central chest pain which radiates to his neck and left arm. His normal medications include normally aspirin, a diuretic, a ch...
