Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating arrhythmia, such as radiofrequency catheter ablation, face challenges in determining the optimal invasion site before surgery, and antiarrhythmic agents' effects vary significantly based on individual ion channel characteristics, making it difficult to select the most effective and safe treatment for each patient.
Innovation Solution
A system and method that measure cardiac action potentials using a catheter, determine ion channel characteristics without obtaining cardiomyocytes, and simulate the treatment effect of an antiarrhythmic agent selected based on these characteristics, allowing for personalized treatment evaluation without direct application of the agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cardiomyocyte sampling is performed to determine ion channel characteristics, then measurement precision is improved, but object-affected harmful factors increase due to invasive procedures and patient risk
Solution Approach 1:
The patent uses computational models that copy and simulate the behavior of ion channels in cardiomyocytes, allowing determination of ion channel characteristics without direct cellular sampling. The model replicates the electrical properties and responses of actual cardiomyocytes to various antiarrhythmic agents, providing accurate predictions while eliminating invasive procedures.
Solution Approach 2:
The patent replaces the mechanical/biological process of physical cardiomyocyte sampling and laboratory analysis with a computational simulation system. The computer-based model processes clinical data and electrocardiogram measurements to determine ion channel characteristics, substituting physical extraction and analysis with digital computation and virtual experimentation.
2Measurement precision
If antiarrhythmic agents are applied directly to patients for treatment evaluation, then treatment effectiveness is determined, but object-affected harmful factors increase due to potential adverse reactions
Solution Approach 1:
The patent performs preliminary computational evaluation of treatment effects by simulating the interaction between selected antiarrhythmic agents and the patient's specific ion channel characteristics before actual administration. This pre-treatment simulation predicts efficacy and potential adverse reactions, allowing clinicians to select the most appropriate agent without exposing the patient to ineffective or harmful substances.
Solution Approach 2:
The patent creates a virtual copy of the patient's cardiac electrical system through computational modeling, allowing safe testing of various antiarrhythmic agents in silico. The simulation replicates the patient's specific ion channel profile and predicts drug responses, providing a risk-free environment for treatment evaluation before clinical application.
3Reliability
If radiofrequency catheter ablation is used to treat arrhythmia, then treatment effectiveness is improved, but device complexity and difficulty of operation increase due to the need to determine optimal invasion sites
Solution Approach 1:
The patent performs preliminary computational analysis to identify the optimal ablation sites before the actual surgical procedure. By simulating the electrical propagation and identifying critical pathways in the patient's specific cardiac anatomy, the system provides a pre-planned roadmap for the ablation procedure, reducing intraoperative decision-making complexity and improving procedural efficiency.
Solution Approach 2:
The patent introduces a computational modeling system as an intermediary between the patient's anatomical data and the ablation procedure. This intermediate layer processes complex electroanatomical relationships and translates them into actionable guidance for the surgeon, simplifying the operational complexity while maintaining treatment effectiveness.

AI summary
A system and method for evaluating effects of an antiarrhythmic agent. The system includes: an action potential measurement unit for measuring a cardiac action potential of a patient; an ion channel characteristics determination unit for determining ion channel characteristics of the patient using the cardiac action potential; and an antiarrhythmic agent effect evaluation unit for simulating a treatment effect of an antiarrhythmic agent by reflecting characteristics of the antiarrhythmic agent on the determined ion channel characteristics of the patient. The system can conveniently determine the patient's ion channel characteristics by measuring the cardiac action potential of the patient, thereby preventing the risk of gathering cardiomyocytes of the patient. In addition, the system can simulate a treatment effect of an antiarrhythmic agent that usually exhibits a different effect and a different level of safety depending on an individual's ion channel characteristics, without being directly applied to the patient.
