    摘要: Methods and apparatus for accurately and painlessly measuring the impedance between defibrillation electrodes implanted in a patient utilize a high current test pulse delivered with a sufficiently high current to produce an accurate measurement of the defibrillation electrode impedance while limiting the duration of the test pulse such that the pain sensing cells in the patient do not perceive the test pulse. In one embodiment, the test pulse is generated from the high voltage transformer without storing energy in the high voltage capacitors and is delivered to the defibrillation electrodes in the patient utilizing the high voltage switching circuitry.

    摘要: An implantable, bipolar or multipolar pacing lead comprises a lead body having a proximal end and a distal end portion. A tip electrode is disposed at a distal extremity of the distal end portion of the lead body, the tip electrode being electrically coupled to a first terminal contact on a connector assembly attached to the proximal end of the lead body. The lead further comprises one or more ring electrodes positioned along the distal end portion of the lead body proximally of the tip electrode, with each ring electrode being electrically coupled to a terminal contact on the connector assembly and each ring electrode having distal and proximal ends. The electrical resistance of each ring electrode adjacent each of the ends is greater than that of the portion of the ring electrode between the ends. The reduction of the current density at the higher resistance ends of the ring electrode increases the magnitude of the current that must be delivered to the ring electrode in order for it to pace anodally, thereby inhibiting the tendency to so pace. Also disclosed is an implantable cardiac pacing system incorporating the aforedescribed lead. Further disclosed is a method of fabricating an electrically conductive ring electrode for a pacing lead, the ring electrode having opposed ends, the method comprising forming adjacent each of the opposed ends of the ring electrode a region having an electrical resistance that is greater than that of the portion of the ring electrode between said regions.

    摘要: An implantable cardiac device and method monitors a patient's body impedance so as to diagnose medical problems, such as fluid balance problems in congestive heart failure patients. The device monitors the patient's position and determines an appropriate time for collecting body impedance data when the patient is in repose. The device then obtains a series of measurements of thoracic impedance by transmitting a signal on at least one lead, which may be a standard pacemaker lead, and sensing a signal received at a different point. The series of measurements are combined to obtain desired representations of thoracic impedance. In an embodiment, impedance is represented by an extracellular water (ECW) resistance value and an intracellular water (ICW) resistance value determined using a Cole calculation method.
