    摘要： Techniques for transmitting diagnostic information stored in an implantable medical device (IMD) based on patient hospitalization are described. For example, the IMD may transmit higher resolution diagnostic information to a clinician and/or an external device during a hospitalization period to aid the clinician in evaluating heart failure treatment and when discharge is proper. This higher resolution diagnostic information may include one or more patient metrics automatically generated and transmitted by the IMD at least once every two hours. During a post-hospitalization period, the IMD may transmit lower resolution diagnostic information to a clinician that indicates a risk level of re-hospitalization. The lower resolution diagnostic information may include the risk level and/or patient metrics once a day, for example. In this manner, the IMD transmitted diagnostic information may be tailored to the specific heart failure monitoring needed by the patient.

    摘要： Techniques for generating a heart failure risk score with detected patient metrics are described. An implantable medical device (IMD) may collect and store patient data regarding therapy use statistics, thoracic impedance, heart rate, patient activity, and other patient metrics. Based on the number of patient metrics exceeding their respective metric thresholds, the IMD may automatically generate a risk score that indicates the likelihood that the patient will suffer from heart failure. The risk score may identify a patient as requiring immediate medical attention to reduce the risk of heart failure. The IMD may push an alert of the heart failure risk score to a clinician, and the clinician may review the patient metric data on an external device. In some examples, a clinician may prioritize patient treatment with a presented list ranking patients with the most severe heart failure risk scores.

    摘要： An implantable medical device is directed to techniques for applying overdrive pacing to one or both atria following termination of an AF episode, to prevent a recurrent AF episode. The implantable medical device such as a pacemaker applies overdrive pacing according to overdrive pacing parameters, and sets the parameters as a function of the response of the patient to overdrive pacing. The parameters may be adjusted upward or downward, so that overdrive pacing may be applied effectively but not over-applied.

    摘要： Changes in physiologic parameters may be detected in a patient by measuring the impedance of a tissue segment located in a selected electrode vector field, storing baseline impedance information based on the measured impedance, detecting changes in impedance characteristics from the baseline impedance information, and providing alerts for changes in the physiologic parameters based on the detected changes in impedance characteristics. In some situations, detecting the changes in impedance characteristics involves detecting changes in morphology of an impedance waveform, such as a cardiac component of an impedance waveform, a respiratory component of an impedance waveform, and the phase angle of the complex impedance.
