摘要： Apparatus and methods are provided for analyzing an episode stored by an implantable medical device (IMD) using prior probability and conditional probability information to determine the likelihood of a particular diagnosis for a given stored episode. Certain embodiments include retrieving information about a stored episode from an IMD, including an episode metric, and retrieving domain expert information about potential diagnoses and episode metrics to determine the likelihood that the stored episode was due to a particular potential diagnosis. Certain embodiments also include retrieving patient information including a patient metric, such as patient demographics, or patient history. Certain embodiments of the invention include the ability to automatically or manually update or change the domain expert information.

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： An implantable cardioverter defibrillator (ICD) automatically determines whether to use electrogram (EGM) signals sensed by a true bipolar electrode pair or those sensed by an integrated bipolar electrode pair. EGM signals from both the true bipolar pair and the integrated bipolar pair are simultaneously sensed and compared to determine which pair produced more accurate sensing of cardiac events. The more accurate source of EGM signals is selected and used in determining the therapy to be delivered.
