Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing events determined by implantable devices, such as cardiac monitors, often result in false positives, leading to inadequate medical responses and unnecessary patient unease.
Innovation Solution
A method that verifies events determined by implantable devices by considering the type of event and analyzing heart episodes associated with those events, using additional verification steps tailored to the specific type of event, and potentially involving external devices with greater computational power.

Engineering Contradiction Analysis
1Measurement precision
If generic verification steps are used for all events, then the verification process is simple and consistent, but the accuracy of event verification is insufficient leading to false positives
Solution Approach 1:
The patent applies local quality by implementing verification processes that are specific to each event type rather than using a uniform approach. Different verification algorithms and parameters are selected based on the characteristics of the detected event, thereby improving verification accuracy for each specific event type while maintaining a manageable overall system structure through modular design.
Solution Approach 2:
The patent utilizes parameter changes by adapting verification thresholds, time windows, and analysis parameters according to the type of event detected. For example, different arrhythmia types require different verification criteria, and the system dynamically adjusts these parameters to optimize detection accuracy for each specific condition.
2Reliability
If additional verification steps are implemented, then false positives are reduced, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by performing initial event detection and classification before implementing detailed verification steps. This allows the system to prepare appropriate verification algorithms in advance based on the preliminary event type, reducing the actual verification time when a true positive is detected while maintaining high reliability.
Solution Approach 2:
The patent implements partial verification actions by applying different levels of verification intensity based on event characteristics. For high-risk events, more comprehensive verification is performed, while for lower-risk events, streamlined verification suffices. This balances reliability improvement with time efficiency by avoiding excessive verification for all events uniformly.
