Wearable Pulse Data Display for Arrhythmia Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices inaccurately display sleep stage data due to arrhythmia affecting pulse data, which is not controlled by the autonomic nervous system, leading to incorrect physiological data being displayed.
Innovation Solution
The electronic device acquires pulse data, determines abnormal pulse data corresponding to arrhythmia, calculates a ratio of the accumulated duration of abnormal pulse data, and adjusts the display of physiological data features based on this ratio, using acceleration detection methods for accurate data parsing and displaying relevant physiological parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device displays physiological data based on pulse data, then the user can obtain sleep stage information, but the displayed data becomes incorrect when the user has arrhythmia
Solution Approach 1:
The system dynamically adjusts the data processing approach based on the detected arrhythmia condition. When arrhythmia is detected, the system switches from using pulse data to using acceleration data for sleep stage detection, ensuring reliability under varying physiological conditions
Solution Approach 2:
The system changes the input parameter from pulse data to acceleration data when arrhythmia is detected. This parameter substitution allows the system to maintain accurate sleep stage detection even when pulse data becomes unreliable due to arrhythmia
2Measurement precision
If the device uses pulse data for sleep stage detection, then the detection method is simple, but the accuracy decreases when arrhythmia is present
Solution Approach 1:
The system introduces an intermediary condition (arrhythmia detection result) that determines which data processing path to follow. This intermediary mechanism enables the system to select the appropriate detection method based on the user's physiological state, improving accuracy without permanently increasing complexity
3Loss of information
If the device displays all physiological feature parameters, then the information is comprehensive, but the data may be incorrect when arrhythmia duration is significant
Solution Approach 1:
The system dynamically determines the set of displayable parameters based on the arrhythmia duration ratio. When the ratio exceeds the threshold, the system restricts displayed parameters to only those derived from acceleration data, preventing display of incorrect data while maintaining information completeness for valid parameters

AI summary
This application relates to the field of electronic technologies, and discloses a data display method and an electronic device. In this application, the electronic device acquires pulse data within a first time period, and after determining that the pulse data includes abnormal pulse data, determines a ratio of a second duration to a first duration. The first duration is a length of the first time period, and the second duration is an accumulated duration of the abnormal pulse data. When the ratio is greater than a first preset value, the electronic device displays first physiological data, the first physiological data including a first physiological feature parameter, thereby ensuring that the physiological data displayed to a user is correct, and improving the user experience.
