Intracardiac Device Storing Electrograms for Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring and verifying cardiac device functionality require extensive time and effort from healthcare providers, as they need to perform and analyze tests in-clinic, which can be inefficient and burdensome, especially when verifying out-of-clinic measurements where electrogram data is not available.
Innovation Solution
An intracardiac stimulation device capable of measuring and storing test data associated with cardiac events, including event electrograms and marker data, allowing for efficient storage and retrieval of relevant data for later verification by healthcare providers, reducing the need for in-clinic analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the device stores only numerical test results without electrogram data, then device memory usage is reduced, but the physician cannot verify the validity of the test data
Solution Approach 1:
The patent extracts and stores only the essential verification elements (selected electrogram segments and markers) rather than complete continuous data, allowing verification capability while reducing memory consumption
Solution Approach 2:
The device automatically performs preliminary data processing and selection during the test, pre-identifying and storing only the relevant electrogram segments and markers that will be needed for verification, eliminating the need for full data storage
2Reliability
If the physician performs complete test analysis in-clinic with full electrogram review, then data verification is thorough, but the time commitment and patient care provider interaction increase substantially
Solution Approach 1:
The device performs self-verification by automatically comparing test results with stored electrogram data and markers, generating verification status indicators that reduce the physician's time commitment while maintaining thoroughness
Solution Approach 2:
The device performs preliminary analysis and verification before the physician reviews the data, pre-processing the electrogram segments and markers to highlight only the critical verification points that require physician attention
3Reliability
If continuous electrogram data is stored for all cardiac events, then complete verification is possible, but device memory is consumed excessively
Solution Approach 1:
The patent segments the continuous electrogram data into discrete, relevant segments associated with specific cardiac events and test measurements, storing only these segmented portions rather than continuous data streams
Solution Approach 2:
The device applies different storage qualities to different data portions, storing high-fidelity electrogram segments only for events relevant to test verification while using compressed or summary representations for other data

AI summary
In a possible implementation, a method for cardiac testing is provided which includes measuring test data associated with cardiac events and storing the test data in an intracardiac stimulation device. The method further includes acquiring event electrograms corresponding with the test data and storing the event electrograms corresponding with the test data in the intracardiac stimulation device. In a possible implementation, marker data is stored associating event electrograms with measured test data, which may identify the event electrograms used for measuring the test data and/or identify when adjacent event electrograms are not contiguous. In some implementations, the test data may be measured and stored in an out-of-clinic test, and the test data and the corresponding event electrograms may be later retrieved from the intracardiac stimulation device and presented on a visual display.
