Solution Overview
Problem
Conventional electrocardiogram-based methods for screening cardiac ventricular hypertrophy (VH) have low sensitivity and are unreliable, particularly for right VH, as they rely solely on 12-lead electrocardiogram data.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrocardiogram-based methods are used for VH screening, then the screening process is simple and quick, but the sensitivity is lower than 30% and reliability is poor
Solution Approach 1:
The patent combines multiple data sources including electrocardiogram data, physiological parameters, and imaging data into a unified machine learning model. This integration of heterogeneous data types enables comprehensive VH screening with significantly improved sensitivity and reliability compared to conventional single-modality approaches.
Solution Approach 2:
The patent creates a composite screening model that integrates multiple types of medical data (electrocardiographic, physiological, and imaging parameters) similar to how composite materials combine different substances to achieve superior properties. This composite approach enables the model to capture complex patterns that single data type cannot detect, achieving sensitivity exceeding 90%.
2Measurement precision
If machine learning models with multiple parameters are used, then screening accuracy is improved, but data processing complexity and computational requirements increase
Solution Approach 1:
The patent performs preliminary data preprocessing including normalization, feature extraction, and quality control checks before feeding data into the machine learning model. This preliminary processing organizes raw data into standardized formats, reducing computational complexity during model execution while maintaining high screening accuracy.
Solution Approach 2:
The patent replaces complex manual data processing and interpretation with automated machine learning algorithms. The model automatically identifies patterns and makes diagnostic predictions, substituting manual analytical processes with computational intelligence that handles complexity efficiently and consistently.
Data Source
AI summary
A system for establishing a model for cardiac ventricular hypertrophy (VH) screening includes a storage and a processor. The storage stores multiple pieces of subject data respectively associated with multiple subjects. Each of the pieces of subject data contains a basic physiological parameter group, an electrocardiographic parameter group, and an actual VH condition that corresponds to a left or right ventricle of the subject associated with the piece of subject data. The processor is electrically connected to the storage, splits the pieces of subject data into a training set and a test set, and establishes the model for VH screening based on the pieces of subject data in the training set by using machine learning techniques.
