    摘要: A defibrillator/monitor (10) is disclosed employing a motion detection circuit 18 and control and processing circuit (20) that cooperatively detect motion at a patient-electrode interface. In that regard, an impedance measurement circuit (24) produces an output indicative of the impedance of the interface. This output is then processed by a number of filter elements before being analyzed by a motion detection routine (52). The motion detection routine includes subroutines (62 and 64) that compare the impedance against distinct upper and lower limits and then monitor the time at which the signal is above and below the limits. Basically, motion is indicated if the signal undergoes relatively large variations for a short time, or smaller variations for a longer time. A third motion clear subroutine (66) is used to determine when motion is no longer detected. Finally, a similar scheme (102) is employed to quickly restore the various filter elements after saturation.

    摘要: Die Defibrillation eines Herzens erfolgt in bekannter Weise dadurch, daß eine Ladekapazität über eine steuerbare Schalteinrichtung mit im Bereich des Herzens angeordneten Elektroden verbunden wird und dabei über das Herzgewebe entladen wird.
    Um dabei den Anfangsstrom auf einen unschädlichen Wert zu begrenzen, weist die steuerbare Schalteinrichtung (10) zwei Kontakte (25,29) auf, zwischen denen ein unter der Einwirkung eines elektromechanischen Wandlers (25,33) deformierbares Schaltstück (32), beispielsweise ein Quecksilbertropfen, in der Weise angeordnet ist, daß das Schaltstück (32) bei einer vorgegebenen Auslenkung des elektromechanischen Wandlers (25,33) die beiden Kontakte (25,29) miteinander verbindet und bei einer von der vorgegebenen Auslenkung ausgehenden Änderung der Auslenkung den elektrischen Widerstand zwischen den Kontakten (25,29) verändert. Die Ansteuerung der steuerbaren Schalteinrichtung (10) erfolgt durch Einschaltimpulse mit einer zum Einstellen des gewünschten elektrischen Widerstands zwischen den Kontakten (25,29) veränderbaren Impulshöhe.

    摘要: An energy transfer circuit (40) for delivering a cardiac defibrillation pulse to a patient (50). An energy storage capacitor (16) is coupled to a pair of electrodes (52a, 52b) through an electronic switch (42). The electronic switch is controlled by a control circuit (20). A current shunt 56 is connected in parallel with a pair of defibrillation electrodes (52a, 52b) to divert a leakage current that flows through the electronic switch away from the patient when a defibrillation pulse is not being delivered. A current sensor (64) or a voltage sensor (72) provide a feedback signal to the control circuit to regulate the energy of the defibrillation pulse that flows through the patient.

    摘要: Disclosed is a method for the diagnosis of conductor anomalies, such as an insulation failure resulting in a short circuit, in an implantable medical device, such as an implantable cardioverter defibrillator (ICD). Upon determining if a specific defibrillation pathway is shorted, the method excludes the one electrode from the defibrillation circuit, delivering defibrillation current only between functioning defibrillation electrodes. Protection can be provided against a short in the right-ventricular coil-CAN defibrillation pathway of a pectoral, transvenous ICD with a dual-coil defibrillation lead. If a short caused by an in-pocket abrasion is present, the CAN is excluded from the defibrillation circuit, delivering defibrillation current only between the right -ventricular and superior vena cava defibrillation coils. Determination that the defibrillation pathway is shorted may be made by conventional low current measurements or delivery of high current extremely short test pulses.
