    摘要: Systems, devices, and methods detect or classify tachyarrhythmias or make a therapy decision. A tachyarrhythmia can be classified using a rhythm discrimination parameter having a value. In certain examples, the value of the rhythm discrimination parameter can be adjusted using a relationship between a detected atrial rate and a detected ventricular rate, or the value can be adjusted using information about at least one of the atrial rate or the ventricular rate in addition to using the relationship between the atrial rate and the ventricular rate. These techniques can improve the specificity of arrhythmia detection or classification, allow anti-tachyarrhythmia therapy to be better tailored to the particular tachyarrhythmia, or provide more automatic operation making it easier for a physician to use an implantable device.

    摘要: A system comprising an implantable medical device includes a ventricular heart signal sensing circuit, a pacing therapy circuit, and a controller circuit coupled to the signal sensing circuit and the therapy circuit. The controller circuit is operable to detect a ventricular tachycardia heart rhythm from the cardiac signal, measure an amount of time the heart signal is one of inside or outside of an effective amplitude band, and initiate ATP therapy if the measured amount of time is less than a threshold amount of time.

    摘要: An implantable medical device senses a plurality of electrograms from substantially different atrial locations, detects regional depolarizations from the electrograms, and analyzes timing relationships among the regional depolarizations. The timing relationships provide a basis for effective therapy control and/or prognosis of certain cardiac disorders. In one embodiment, an atrial activation sequence is mapped to show the order of occurrences of the regional depolarizations during an atrial depolarization for classifying a detected tachyarrhythmia by its origin. In another embodiment, conduction time between two atrial locations is measured for monitoring the development of an abnormal atrial conditions and/or the effect of a therapy.

    摘要: This invention is a hydrocarbon gel concentrate containing a high polymer load and a polar compound. The method of the present invention allows for increasing polymer load of a mineral oil gel through the addition of a polar compound as a processing aid during gel formation such that the viscosity of the resulting hydrocarbon gel concentrate is mixable at processing temperature, thereby allowing dilution of the hydrocarbon gel concentrate with additional hydrocarbon oil.

    摘要: A binding assay product (1) for detecting the presence of an analyte in a sample comprising a labelling module (5), a label, a capture module (9) and a visualization module (10). The labelling module (5) comprises a first binding component capable of binding the analyte. The label is connectable to the first binding component. The capture module (9) comprises a second binding component capable of binding the analyte. The visualization module (10) is for detecting the first binding component connected to the label and bound to the second binding component via the analyte. The labelling module and the capture module comprise a fluid conducting medium in which the binding components are embedded. The labelling module (5), the capture module (9) and the visualization module (10) together define a flow path along which the sample is capable of flowing.
