摘要： An implantable cardiac device is configured to classify cardiac arrhythmias using a plurality of arrhythmia discrimination algorithms. Data is provided that is associated with a plurality of cardiac arrhythmic episodes for which a cardiac electrical therapy was delivered or withheld by the implantable medical device based on the plurality of arrhythmia discrimination algorithms. A metric for each of the arrhythmic episodes is computed. The metric defines a measure by which the implantable cardiac device properly classified the arrhythmia. Potentially misclassified arrhythmic episodes of the plurality of cardiac arrhythmic episodes for which cardiac electrical therapy was inappropriately delivered or withheld are algorithmically identified using the metric.

摘要： Systems and methods provide for selection of automatic capture verification modes. A number of capture verification modes are evaluated, wherein at least one of the capture verification modes has a distinct temporal relationship between delivery of a pacing pulse and detection of capture of heart tissue by the pacing pulse than the other capture verification modes. One or more capture verification modes are selected based on the evaluation. Capture verification is implemented using the selected one or more capture verification modes.

摘要： In connection with capture detection for a heart chamber with backup pacing in a contralateral heart chamber, a cardiac signal of the first heart chamber is sensed following delivery of a pacing pulse. The cardiac response of the first heart chamber to the pacing pulse is classified based on one or more features of the sensed cardiac signal. A backup pacing pulse is delivered to a second heart chamber contralateral to the first heart chamber. For example, the timing of the delivery of the backup pacing pulse may be based on the expected or detected timing of the features used to classify the cardiac pacing response. The backup pace may be delivered within a detection window used for sensing the features indicative of the cardiac pacing response.

摘要： Methods and systems for arranging and labeling cardiac episodes based on acquired cardiac episode data are described. Cardiac episodes are algorithmically arranged based on one or more discriminating features of the episode data. A user is presented with at least one episode selected from the arrangement of cardiac episodes. The user inputs a label that characterizes the selected episode. The label is algorithmically appended to the data of the selected episode and to other episodes of the arrangement of cardiac episodes based on the discriminating features.

摘要： The waveform morphology of a propagated pacing response signal may be adjusted to achieve a waveform morphology that enhances cardiac pacing response determination. One or more pacing intervals may be adjusted to achieve at least one cardiac pacing response waveform morphology that enhances determination of the cardiac pacing response. The heart is paced using the one or more adjusted pacing intervals and the cardiac response to the pacing is determined. The one or more adjusted pacing intervals may include an atrioventricular pacing delay, an interatrial pacing delay, an interventricular pacing delay, or other inter-chamber or inter-site pacing delays. Adjusting the one or more pacing intervals may be used to increase a difference between a first waveform morphology associated with multi-chamber capture and a second waveform morphology associated with single chamber capture.

摘要： Methods and systems involve determining the cardiac response to pacing pulses. The variability cardiac signal features detected during initialization is used to establish a variability threshold. A cardiac signal associated with a pacing pulse is sensed and one or more features of the cardiac signal are detected. The variability of the one or more features is compared to the variability threshold. The cardiac response to the pacing pulse is determined based on the feature variability.
