    摘要: A subcutaneous implantable cardiac device system applies defibrillation currents in pathways aligned with the heart's own electrical system to decrease defibrillation thresholds. In one implementation, one or more subcutaneous sensors detect ventricular fibrillation. Positioning of subcutaneous sensors and filtering result in improved sensing with reduced noise. A subcutaneous patch component of the system that is in communication with a subcutaneous pacemaker or cardioverter-defibrillator may perform the sensing and apply the defibrillation. The subcutaneous patch may include one or more electrodes that perform both sensing and defibrillation. Variations of the subcutaneous patch may include battery and capacitor for generating onboard defibrillation current and may also include a microprocessor for advanced programmable operation.

    摘要: Dynamic overdrive pacing adjustment techniques are described for use in implantable cardiac stimulation devices. In a first technique, an overdrive pacing unit of a microcontroller of the implantable device operates to optimize various control parameters that affect overdrive pacing so as to achieve a desired degree of overdrive pacing for the particular patient in which the stimulation device is implanted. Parameters to be optimized include the number of overdrive beats paced once overdrive pacing is trigged, the overdrive pacing response function, the recovery rate, and various base rates. The control parameters are adjusted in a hierarchical order of priority until the desired degree of overdrive pacing is achieved. Adjustment of the number of overdrive beats, the recovery rate, and various base rates is iteratively performed by using incremental numerical adjustments. Adjustment of the overdrive pacing response function may be performed by selecting among a set of fixed predetermined linear response functions. In a second technique, the overdrive pacing unit operates to optimize the shape of a single non-linear dynamic overdrive pacing response function so as to achieve the desired degree of overdrive pacing for the patient. The second technique may either be employed alone or in combination with the first, hierarchical optimization technique.
