摘要： A defibrillator (10) for providing a constant low pulsed current to a patient's heart has a high voltage capacitor (19) for storing electrical energy. An inductor (22) connected to the capacitor (19) smooths out the discharge curve and produces a low current low frequency defibrillator pulse supplied to a patient's heart. The pulse is usually biphasic.

摘要： The invention provides a method and circuit for forming an electrotherapy current wave form. A charge storage device located externally of a patient's body is charged, and is discharged through the patient's body (24) through at least two discharge electrodes (21, 23) connected by electrical circuitry to opposite poles of the charge storage device. A continuous discharge of the charge storage device through the electrodes is controlled so as to produce at least one phase of a current wave form that includes a ripple (14). The ripple has a height less than one third of the height of the peak current of the phase. The current wave form has a sensing pulse portion (10) that is integral with the therapeutic discharge portion of the current wave form.

摘要： A method and apparatus for delivering a truncated damped sinusoidal external defibrillation waveform, which when applied through aplurality of electrodes positioned on a patient's torso will produce a desired response in the patient's cardiac cell membranes, is provided. The external defibrillator is utilized for applying a damped sinusoidal waveform having a first waveform phase, and a second waveform phase to a pair of electrodes. The external defibrillator has a first capacitive component (C1), a first inductive component (L1), a first truncating switch, and waveform control circuitry. The waveform control circuitry of the defibrillator controls the first and second truncating switches, such that the duration of the second phase waveform delivered by the second charge storage component, is greater than the duration of the first phase waveform delivered by the first charge storage component.

摘要： A staged energy storage system (40) provides electrical energy to an implantable cardioverter defibrillator device by using the combination of a first stage energy source (45), and a second stage energy concentration system (50). The second stage energy concentration system (50) allows for either a lower density and/or lower voltage energy source to be used as the first stage energy source (45), thereby decreasing the battery cost, size and weight, or alternatively, for multiple closely spaced countershock pulses to be delivered. In one embodiment, the second stage energy concentration system (50) comprises a rechargeable battery (50). In another embodiment, the second stage energy capacitor system (50) comprises a high energy density capacitor system.

摘要： A practical and effective prophylactic implantable cardioverter defibrillator (ICD) that has the potential to benefit a large number of patients with less severe cardiac conditions who now lack the opportunity to be served in a practical way by existing ICD systems. Unlike existing ICD systems, the prophylactic ICD (17) is designed to deliver between about 100 to 200 shocks, with each shock having a maximum delivered energy value of only about 25 joules. As a result, the initial stored energy requirements of the prophylactic ICD system (17) are less than about 12,000 joules, and both the battery (28) and the capacitor systems (26, 27) can be significantly smaller than existing ICD system. The smaller battery (28) and capacitor systems (26, 27) produce in an implantable device having a physical size small enough to permit implantation of the device in the pectoral region. By using the particular ranges of number of shocks and maximum energy value for each shock to design the ICD system, the result is a practical prophylactic ICD system (17) that will provide effective prophylactic therapy for prospective cardiac incidents in patients with less severe cardiac conditions.
摘要翻译：一种实用且有效的预防性植入式心律转复除颤器（ICD），其潜在的益处是对现有ICD系统缺乏以实际可行方式服务的心脏状况较差的患者。与现有的ICD系统不同，预防性ICD（17）被设计为提供约100至200次冲击，每次冲击的最大输送能量值仅为约25焦耳。因此，预防性ICD系统（17）的初始存储能量需求小于约12,000焦耳，并且电池（28）和电容器系统（26,27）都可以显着小于现有的ICD系统。较小的电池（28）和电容器系统（26,27）在可植入装置中产生，其具有足够小的物理尺寸以允许将装置植入胸部区域。通过使用每次冲击的特定数量范围和每次冲击的最大能量值来设计ICD系统，结果是一种实用的预防性ICD系统（17），将为心脏不良状况患者的预期心脏事件提供有效的预防性治疗。
