    摘要: The disclosed embodiments relate to a system and method for assuring validity of monitoring parameters in combination with a therapeutic device. An exemplary embodiment of the present technique comprises perturbing a treatment administered to a patient, measuring at least one parameter of the patient reflecting the underlying physiological state and associated with the treatment, and comparing the perturbations of the treatment to measurements of the at least one parameter to determine if the perturbations to the treatment are reflected by the parameter.

    摘要: Provided herein are implantable systems, and methods for use therewith, for monitoring a patient's pre-ejection interval (PEI). A signal indicative of cardiac electrical activity and a signal indicative of changes in arterial blood volume are obtained. One or more predetermined features of the signal indicative of cardiac electrical activity and the signal indicative of changes in arterial blood volume are detected. The patient's PEI is determined by determining an interval between the predetermined feature of the signal indicative of cardiac electrical activity and the predetermined feature of the signal indicative of changes in arterial blood volume.

    摘要: Evaluation of an implanted electrical lead condition includes comparing electrogram template features with test electrogram features. The evaluating also includes determining the implanted electrical lead condition based solely on the electrogram comparison. The compared test electrogram features and template electrogram features may be atrial amplitudes and ventricular amplitudes. The sensing may be with a quad polar lead. The compared test electrogram features and electrogram template features may account for different patient postures and/or may account for respiration modulation.

    摘要: Implantable systems, and methods for use therewith, are provided for monitoring a patient's diastolic function and/or heart failure (HF) condition. A signal indicative of changes in arterial blood volume and a signal indicative of electrical activity of the patient's heart are obtained. Beginnings of diastolic periods can be detected based on a feature of the signal indicative of changes in arterial blood volume. Ends of the diastolic periods can be detected based on a feature of the signal indicative of electrical activity of the patient's heart, or on the signal indicative of changes in arterial blood volume. Diastolic periods (DPs), isovolumic relaxation times (IVRTs) and/or diastolic filling times (DiFTs) can be estimated based on the detected beginnings of the diastolic periods and detected ends of the diastolic periods. The patient's diastolic function and/or HF condition (and/or changes therein) can be monitored based on the estimates of DP, IVRT and/or DiFT.

    摘要: A sensor for pulse oximetry or other applications utilizing spectrophotometry may be adapted to reduce motion artifacts by fixing the optical distance between an emitter and detector. A flexible sensor is provided with a stiffening member to hold the emitter and detector of the sensor in a relatively fixed position when applied to a patient. Further, an annular or partially annular sensor is adapted to hold an emitter and detector of the sensor in a relatively fixed position when applied to a patient. A clip-style sensor is provided with a spacer that controls the distance between the emitter and detector.
