    摘要: An electrotherapy circuit administers to a patient a current waveform. The electrotherapy circuit includes a charge storage device, at least two discharge electrodes connected by electrical circuitry to opposite poles of the charge storage device, a sensor that senses a patient-dependent electrical parameter (such as a patient impedance sensor), and a control circuit. The control circuit is connected to the sensor and the charge storage device and controls discharge of the charge storage device through the electrodes. The discharge of the charge storage device includes a current waveform having a sensing pulse portion, with insufficient energy for performing therapy, during which the sensor senses a patient-dependent electrical parameter (such as patient impedance), and a therapeutic discharge portion, with sufficient energy for performing therapy, having an initial discharge current controlled by the control circuit based on the patient-dependent electrical parameter (such as patient impedance) as sensed by the sensor. The sensing pulse portion has a discharge current that is at least about one-third of the initial discharge current of the therapeutic discharge portion.

    摘要: The invention provides a method and circuit for forming an electrotherapy current waveform. A charge storage device located externally of a patient's body is charged, and is discharged through the patient's body through at least two discharge electrodes 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 waveform that includes a ripple. The ripple has a height less than one-third of the height of the peak current of the phase, and the difference between the peak current of the phase and the lowest current of the phase is less than one third of the peak current of the phase. The current waveform has a sensing pulse portion that is integral with the therapeutic discharge portion of the current waveform.

    摘要: Method and apparatus for determining the current in a defibrillation pulse discharge circuit 30 which has an inductor 38 with a characteristic inductance for shaping the defibrillation pulses. A sense winding 136 is wound around the inductor with at least one turn between ends of the winding for developing a sense voltage between the ends in response to the current in the inductor as a defibrillation pulse is discharged by the circuit. This sense voltage is measured, and based on the sense voltage and the characteristic inductance of the inductor, the current in the defibrillation discharge pulse is determined.
