摘要： The present invention is an external defibrillator which controls and manages the formation of defibrillation waveforms. The waveforms are dynamically adjusted and created to be consistent with a myocardial cell response waveform. Dynamic tilt calculations based on time slices and corresponding functions based on best-fit models are used to generate the waveforms. The waveforms are dynamically adjusted to compensate for changes in resistance due to changes in the voltage during delivery of the waveform. The waveforms include a first and a second phase and are formed with minimal delay therebetween.

摘要： In an automatic external defibrillator (AED) having a ventricular fibrillation detector, the ventricular fibrillation detector may generally be defined as a filter containing both an adaptive non-linear section and a linear section. The non-linear section is preferably a complex-domain neural network that can be trained to differentiate between various rhythm patterns and produce linear data for input to the linear section. The linear section is preferably an ongoing, continuous operation based on a sliding window of a predetermined time period, e.g., a tapped time-delay filter. In combination the non-linear section and linear section of the filter operate to detect and extract artifacts from a patient's ECG signal in a substantially accurate fashion so that the determination to deliver a defibrillation pulse may be accurately made.

摘要： A method of generating and applying a defibrillation shock of the present invention includes first applying a defibrillation shock pulse to a patient with an initial predetermined amount of energy not based on a patient-dependent electrical parameter, and while monitoring a patient-dependent electrical parameter. Next, patient transthoracic impedance is determined based on the patient-dependent electrical parameter. Finally, a subsequent predetermined amount of energy is applied to the patient based on the patient transthoracic impedance calculated above and while monitoring the patient-dependent electrical parameter. Subsequent defibrillation shock pulses are applied using a patient impedance based on the patient-dependent electrical parameter observed during the most recent defibrillation shock. In this manner, an optimal combination of charged voltage and the maximum allowed current (under the AAMI defibrillation waveform standard) is applied for a patient's given transthoracic impedance.
