Patent ID: 8521269

Claim:
A method for determining detection parameters in a medical device, comprising: enabling a communication module to retrieve stored episode data accumulated by a medical device configured to sense cardiac signals and detect cardiac rhythm episodes from the sensed cardiac signals in real time using a detection algorithm controlled by a plurality of detection parameters; generating truthed episode classifications from the retrieved episode data by enabling a reclassification module to automatically detect a misclassified episode of the detected cardiac rhythm episodes, determine a reclassification of the misclassified episode, display retrieved episode data corresponding to the misclassified episode, receive an expert input that confirms or rejects the reclassification of the misclassified episode, and store a classification of the automatically detected misclassified episode in accordance with the expert input; enabling a processor to perform a detection simulation for detecting and classifying each of the cardiac rhythm episodes included in the retrieved episode data using the detection algorithm and varied settings of the plurality of detection parameters to obtain simulated episode classifications; generating detection sensitivity and specificity data in response to the detection simulation by comparing the truthed episode classifications to the simulated episode classifications; receiving, by the processor, a detection sensitivity requirement for detecting a tachyarrhythmia and a detection specificity requirement for detecting the tachyarrhythmia; and in response to the sensitivity and specificity data, enabling the processor to identify a recommended detection parameter setting that causes the simulated episode classifications to meet the detection sensitivity requirement and the detection specificity requirement.
