Abstract:
1. A method for identifying cardiac arrhythmias that are potentially misclassified by a cardiac device implanted in a patient, the implantable cardiac device configured to classify cardiac arrhythmias using a plurality of arrhythmia discrimination algorithms, the method comprising: providing data associated with a plurality of cardiac arrhythmic episodes for which a cardiac electrical therapy was delivered or withheld by the implantable cardiac device based on the plurality of arrhythmia discrimination algorithms; computing a metric for each of the arrhythmic episodes, the metric defining a measure by which the implantable cardiac device properly classified the arrhythmia; and algorithmically identifying potentially misclassified arrhythmic episodes of the plurality of cardiac arrhythmic episodes for which cardiac electrical therapy was inappropriately delivered or withheld using the metric.
