    摘要： A defibrillator method and apparatus wherein a patient's measured transthoracic impedance (TTI) is used to control the amount of energy contained in a defibrillation pulse applied to the patient. Prior to delivering a defibrillation pulse, the patient's TTI is measured by an impedance measuring circuit (11). The patient's TTI may also be measured during delivery of a prior defibrillation pulse. A microprocessor (23) uses the measured patient TTI to control the shape of the defibrillation pulse by controlling: (i) the phase duration of the defibrillation pulse; and (ii) the voltage level to which the defibrillator's capacitor bank (15) is charged. The defibrillation pulse shape is controlled so that the energy conveyed by the defibrillation pulse to the patient is near or exceeds a desired value. The desired value may be set by an operator via an energy selector (25). A switch (13) controls the connection of defibrillator electrodes (27a, 27b) to the impedance measuring circuit (11) and the capacitor bank (15).

    摘要： Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator using a measurement of elapsed time. The present invention provides a defibrillator with a timer function. Upon activation of the defibrillator, an internal timer begins to run. By closely associating the activation of the defibrillator with the onset of the patient's attack, and by making allowances for inherent time differences between these events, the timer provides a measure of the elapsed time between the onset of the patient's emergency and the presentation of the defibrillator at the patient's side. Using this measure of elapsed time, the defibrillator determines an appropriate treatment therapy, such as CPR or defibrillation therapy.

    摘要： The invention is directed to techniques for attempting to restore a patient to a normal sinus rhythm. In a patient experiencing asystole or pulseless electrical activity, defibrillation therapy may be ineffective. The invention is directed to techniques for delivering one or more shocks to induce ventricular fibrillation in the patient, followed by one or more defibrillation shocks to restore normal sinus rhythm. A defibrillator may deliver the fibrillation and defibrillation therapies. The invention may also include techniques for estimating the probability that the patient will respond favorably to the defibrillation therapy, and delivering defibrillation therapy when the therapy has a good probability of success.

    摘要： Methods and apparatus are provided for minimizing the inherent time delays within external defibrillators and allowing operators to administer CPR therapy as close in time as possible to the delivery of a defibrillation shock to a patient. The methods and apparatuses utilize timing schemes for initiation and completion of charging or maintaining the charge of an energy storage device of an external defibrillator for at least a portion of a predetermined CPR therapy delivery time.

    摘要： An external cardiac medical device for delivering Cardiac Potentiation Therapy (CPT). Techniques used with the device include initial diagnosis of the patient, delivery of the CPT, and configuration of the external device, so that CPT can be effectively and efficiently provided. In particular, these techniques include initially determining whether a patient should receive CPT, how to set the coupling interval for delivering CPT, how to configure the external medical device to deliver CPT stimulation pulses while not adversely affecting the device's ability to sense a patient's cardiac parameters and/or signals.
