ECG Display Device with Dynamic Waveform Sequence Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printed ECGs are static and cannot be easily switched between standard and Cabrera sequences, leading to potential misdiagnosis in high-stress rescue environments, and they do not allow for real-time changes or secure transfer of annotations.
Innovation Solution
A medical device that displays graphical elements indicative of multiple ECG leads on a screen, allowing users to select between Cabrera and standard formats, update waveforms in real-time, and store and transfer annotations associated with the ECG.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ECG waveforms are printed on paper in a standard nonanatomical sequence, then the ECG can be physically passed between rescuers, but the waveform sequence cannot be changed and may lead to misdiagnosis if the receiving rescuer prefers a different format
Solution Approach 1:
The patent implements dynamic switching between different ECG waveform sequences (standard nonanatomical sequence and Cabrera anatomical sequence) through user-selectable display modes. The system allows rescuers to change the waveform arrangement based on their preference or training, enabling adaptation to different diagnostic needs while maintaining accurate ECG interpretation.
2Ease of operation
If printed ECGs are used in high-stress rescue environments, then the system is simple and portable, but real-time changes cannot be tracked and annotations cannot be securely transferred
Solution Approach 1:
The patent creates a digital copy of the ECG waveform and associated annotations that can be stored, transmitted, and viewed on electronic devices. This digital copy preserves all information including time-stamped annotations made by rescuers, ensuring that no information is lost when transferring care between different locations or personnel.
Solution Approach 2:
The system uses an electronic communication interface as an intermediary to transfer ECG data and annotations between different devices and locations. This intermediary enables secure transmission of both waveform data and annotations, ensuring continuous availability of complete ECG information throughout the care chain.
3Device complexity
If a fixed ECG display format is used, then the device structure is simple, but the system cannot adapt to different rescuer preferences or anatomical sequences
Solution Approach 1:
The display system dynamically reconfigures the arrangement of ECG waveform traces based on user selection. The interface allows switching between standard nonanatomical sequence and Cabrera anatomical sequence, with each sequence presenting the same ECG data in a different spatial arrangement optimized for various diagnostic approaches.
Solution Approach 2:
The display device serves multiple functions by supporting multiple ECG sequence formats within a single system. This multi-functionality allows the same hardware to accommodate different rescuer preferences and training backgrounds, making the device universally applicable across diverse emergency response scenarios without requiring separate specialized equipment.

AI summary
Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.
