Portable ECG Monitoring for Chest Pain Risk Stratification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high frequency of unnecessary visits to emergency rooms for chest pain, resulting in significant psychological and economic burdens on patients and healthcare systems, is not adequately addressed by current wearable technologies, which lack the capability to differentiate cardiac from non-cardiac chest pain and provide accurate risk stratification for emergent medical care.
Innovation Solution
A mobile ECG system that includes a portable device capable of recording and transmitting ECG data to a user device, utilizing cloud-based storage and evidence-based algorithms to compare serial ECGs, assess changes in heart signals, and provide risk stratification, allowing users to make informed decisions about seeking medical care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current wearable technologies are used for chest pain monitoring, then portability and ease of use are improved, but the ability to differentiate cardiac from non-cardiac chest pain and provide accurate risk stratification deteriorates
Solution Approach 1:
The system segments the ECG analysis into multiple specialized algorithms that evaluate different aspects of cardiac function independently, then integrate results for comprehensive risk stratification. This allows the portable device to maintain high diagnostic accuracy by applying targeted analysis methods to specific ECG features.
Solution Approach 2:
The system changes multiple ECG parameters simultaneously (heart rate, rhythm regularity, ST-segment morphology, T-wave characteristics, QT interval) and analyzes their combined patterns. By monitoring multiple parameters rather than single metrics, the portable device achieves hospital-grade differentiation accuracy between cardiac and non-cardiac chest pain.
2Measurement precision
If traditional ECG monitoring systems are used in hospital settings, then diagnostic accuracy and risk stratification capability are improved, but cost and accessibility deteriorate
Solution Approach 1:
The portable ECG device performs self-diagnosis and risk stratification automatically using embedded algorithms that analyze ECG data without requiring hospital infrastructure or specialized personnel. The device provides immediate risk assessment and care recommendations, enabling patients to self-monitor and make informed decisions about seeking medical attention, thereby reducing unnecessary ER visits and associated costs.
Solution Approach 2:
The system replaces complex hospital-based mechanical and infrastructure requirements with a portable electronic device that uses software algorithms for ECG analysis. By substituting the need for hospital equipment, staffing, and facilities with a self-contained portable system, the invention maintains diagnostic accuracy while dramatically reducing cost and improving accessibility.
3Loss of energy
If patients visit the ER for chest pain without accurate risk assessment, then psychological stress and economic costs are reduced in the long term, but immediate healthcare resource utilization and patient anxiety increase
Solution Approach 1:
The portable ECG device provides immediate feedback to patients about their cardiac risk status based on real-time ECG analysis. The system delivers clear, actionable information about whether emergency care is needed, reducing patient anxiety by providing certainty and preventing unnecessary ER visits while ensuring that true emergencies receive prompt attention.
Data Source
AI summary
An electrocardiogram (“ECG”) system is provided. The system includes an ECG device capable of receiving ECG signals from a lead system attached to the user. The ECG device then renders the ECG signals into ECG data, and transmits the ECG data to at least one of a user device, such as a smart phone, or a cloud-based storage system. The user device is capable of rendering the ECG data into an ECG graph, and displaying the ECG graph to the user on an application (“app”). The system also provides for a cloud-based storage system capable storing the ECG data and providing access to the ECG data to the user and to medical personal.
