摘要： Various techniques for detecting cardiac capture in response to a detected lead related condition are described. One example method described includes delivering a pacing therapy to a heart of a patient, periodically determining whether the pacing therapy captures the heart of the patient, detecting a lead related condition, and, in response to the detected lead related condition, increasing a frequency of determining whether the pacing therapy captures the heart.

摘要： The present disclosure is directed to generating and displaying an electrogram (EGM) summary for use by physicians or other clinicians. An implantable medical device (IMD) transmits EGM signal data for a number of cardiac episodes to an external computing device. The external computing device selects a subset of the cardiac episodes for which information or images are displayed to the user. In various examples, cardiac episodes may be selected for display based at least in part on a retrospective analysis classification of the cardiac episode.

摘要： Techniques for determining whether a lead related condition exists based on analysis of a cardiac electrical signal associated with a non-sustained tachyarrhythmia (NST) are described. In some examples, the techniques include determining the duration of intervals between consecutive cardiac events, e.g., R-R intervals, during an NST. The techniques may further include determining one or more metrics based on the durations of the intervals during the NST. Examples of metrics include an average, a minimum, a maximum, a range, a median, a mode, or a mean. A lead related condition is identified based on the values of the one or more metrics, e.g., by comparison to respective thresholds. In some examples, an alert is provided or a therapy modification is suggested if a lead related condition is identified.

摘要： In general, the disclosure relates to techniques for calculating mean impedance values and impedance variability values to detect a possible condition with a lead or device-lead pathway or connection. In one example, a device may be configured to determine an impedance value for an electrical path based on a plurality of measured impedance values for the electrical path, wherein the electrical path comprises a plurality of electrodes, and to determine an impedance variability value based on at least one of the plurality of measured impedance values. The device may be further configured to determine a threshold value based on the determined impedance value and the impedance variability value, compare a newly measured impedance value for the electrical path to the threshold value, and indicate a possible condition of the electrical path based on the comparison.

摘要： A method for identifying and classifying various types of oversensing in implantable medical devices (IMDs), such as implantable cardioverter defibrillators (ICDs), to assist a physician in choosing corrective action to reduce the likelihood of oversensing and inappropriate therapy delivery. Far-field electrogram (EGM) signals are analyzed to detect the occurrence of R-waves, and the result is compared to the number and pattern of R-waves sensed by the IMD and indicated on the marker channel. A marker channel with more sensed R-waves than indicated by analysis of the far-field EGM indicates the presence of oversensing, including double-counting of R-waves, T-wave oversensing, lead malfunction or failure, poor lead connections, noise associated with electromagnetic interference, non-cardiac myopotentials, etc. Identification of the type of oversensing may be determined by analysis of the number and pattern of marker channel sensed R-waves with respect to the timing of the R-waves detected from the far-field EGM.

摘要： In general, the disclosure is directed to techniques for identification and remediation of oversensed cardiac events using far-field electrograms (FFEGMs). Identification of oversensed cardiac events can be used in an ICD to prevent ventricular fibrillation (VF) detection, and thereby avoid delivery of an unnecessary defibrillation shock. Alternatively, or additionally, identification of oversensed cardiac events can be used in an ICD to support delivery of bradycardia pacing during an oversensing condition. In some cases, bradycardia pacing delivered in response to detection of oversensed cardiac events may include pacing pulses from multiple vectors to provide redundancy in the event the oversensing may be due to a lead-related condition.

摘要： In general, the disclosure relates to techniques for providing a combination of stored diagnostic information, including impedance trend data, into one displayable report that may be used to diagnose a possible condition with an implantable medical electrode lead. One example device includes a processor that is configured to obtain impedance trend data for an electrical path, the electrical path comprising a plurality of electrodes, and to obtain additional diagnostic data that is associated with the electrical path, the additional diagnostic data being distinct from the impedance trend data. The device is further configured to combine both the impedance trend data and the additional diagnostic data into a displayable report that indicates whether there is a possible condition with the electrical path. The additional diagnostic data may include non-sustained episode data, sensing integrity data, pacing threshold, and/or electrogram data (such as P-wave amplitude and/or R-wave amplitude data).

摘要： A troubleshooting method can identify potential sources of noise emanating from an implanted portion of a medical system. The method, which may be carried out by the system, for example, according to pre-programmed instructions, includes a step of collecting at least one EGM sample from a sensing pair of electrodes, and an EGM sample from each of a plurality of recording pairs of electrodes. The sensing pair may be formed by first and second electrodes of an implanted lead, and the plurality of recording pairs include pairs formed by each of the lead electrodes and an electrode of an implanted device. Following collection, the EGM samples from the recording pairs may be analyzed for the presence or absence of noise and, then, potential noise sources may be determined.
