AI Technical Summary

Technical Problem

Existing limb-mounted ECG monitors are easily affected by myoelectric noise, which results in a decrease in ECG signal quality and makes it difficult to accurately diagnose atrial fibrillation during activities. PPG sensors cannot accurately distinguish atrial fibrillation from other arrhythmias, making it difficult for existing devices to provide reliable diagnosis of circulatory system diseases in daily life.

Method used

Combining ECG sensors and PPG sensors, the information processing unit obtains ECG signals and pulse wave data. The P wave information and heart rate variability of the ECG signal are used, combined with the heart rate variability of the PPG signal, to achieve accurate diagnosis of atrial fibrillation. Dry electrodes and PPG sensors are used for signal measurement.

Benefits of technology

In daily life, it can reliably monitor and diagnose circulatory system diseases such as atrial fibrillation, improve the reliability and accuracy of data, reduce the impact of myoelectric noise, and realize 24-hour atrial fibrillation monitoring and recording of related indicators.
