ECG Data Relay Using HRV Thresholds to Cut Unneeded Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable ECG measuring devices transmit large volumes of ECG data to medical information systems, including both normal and abnormal data, leading to resource wastage and inefficient diagnosis, as most data collected are not relevant for determining heart-related diseases.
Innovation Solution
A method for selectively transmitting ECG data based on heart rate variability thresholds or trigger signals, allowing only relevant data to be relayed to medical information systems, reducing unnecessary data transmission and improving diagnostic efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If portable ECG measuring devices transmit all detected ECG data to the data collection center, then data completeness is improved, but medical resource waste increases due to analyzing unnecessary normal data
Solution Approach 1:
The patent applies preliminary action by performing ECG data analysis and abnormality detection at the portable device before transmission. The device pre-processes the data, identifies abnormal segments, and only transmits those relevant portions to the data collection center. This preliminary filtering action eliminates the need to transmit and analyze large volumes of normal data, thereby reducing medical resource waste while maintaining data completeness for diagnostic purposes.
2Loss of information
If portable ECG measuring devices transmit all detected ECG data to the data collection center, then data integrity is improved, but transmission time and network bandwidth consumption increase
Solution Approach 1:
The patent applies the extraction principle by separating abnormal ECG data from normal data at the source device. The system extracts only the abnormal segments that require medical attention and transmits them to the data collection center, while normal data remains local or is discarded. This extraction approach maintains data integrity for abnormal cases while dramatically reducing transmission time and network bandwidth consumption by eliminating unnecessary normal data transmission.
3Reliability
If portable ECG measuring devices transmit all detected ECG data, then diagnostic accuracy is improved, but data processing load at the medical information system increases
Solution Approach 1:
The patent applies preliminary action by performing initial data processing and abnormality detection at the portable ECG device before data reaches the medical information system. The device pre-analyzes the ECG data, identifies abnormal segments, and transmits only those relevant portions along with basic patient information. This preliminary processing action maintains diagnostic accuracy by ensuring all abnormal data is captured, while significantly reducing the data processing load at the medical information system since it receives only pre-filtered abnormal data rather than complete raw datasets.
Data Source
AI summary
A method for relaying ECG data is disclosed. The method may selectively transmit part of the ECG data from an ECG detection device to a medical information system server through a mobile communication device. The method may comprise steps of continuously receiving ECG data detected by and sent from the ECG detection device; synchronously calculating heart rate variability corresponding to each consecutive time point of the ECG data; and when a calculated heart rate variability is lower than a threshold, sending all ECG data in a corresponding time period to the medical information system server, until the calculated heart rate variability is not lower than the threshold.
