    摘要: Systems and methods of managing features or functions of an implantable cardiac device involve forming a baseline evoked response template prior to delivery of defibrillation therapy to a patient's heart, and acquiring a post-shock evoked response signal subsequent to defibrillation therapy delivery. The baseline evoked response template is compared to the post-shock evoked response signal. A determination is made whether to enable, disable or adjust a cardiac device feature based on the comparison. The cardiac device feature may be a therapy feature, a monitoring feature, or a diagnostic feature.

    摘要: Methods and systems involve multi-chamber cardiac capture detection utilizing sensing during a cross-chamber refractory period. First and second pacing pulses are delivered to first and second heart chamber. Capture or non-capture of the second heart chamber is determined. Sensing in the first heart chamber is performed to sense for cross-chamber propagation initiated by the second pacing pulse. Capture of the first chamber is detected if capture of the second heart chamber is detected and if the cross-chamber propagation is not detected.

    摘要: An apparatus comprises a therapy circuit that provides a neural stimulation current, an impedance measurement circuit that measures a value of impedance at the output of the therapy circuit, a supply voltage generating circuit that provides an adjustable supply voltage value to the therapy circuit including a first supply voltage value when in a first mode, and a control circuit communicatively coupled to the therapy circuit, the impedance measuring circuit, and the supply voltage generating circuit. The control circuit, upon receiving an indication to exit the first mode, initiates an impedance measurement by the impedance measurement circuit, determines the second supply voltage value using the impedance measurement, and initiates a change from the first supply voltage value to the second supply voltage value. The second supply voltage value is sufficient to operate the therapy circuit and to provide a specified load current value to the measured impedance.
