Abstract
A physiological data detection method is provided. The physiological data detection method includes the following steps. Firstly, an ECG signal and a PPG signal are detected. Then, a plurality of RRI values is calculated according to the ECG signal, and a plurality of PPI values is calculated according to the PPG signal. Thereafter, wrong RRI values are excluded according to the RRI values and/or the PPI values. Then, whether an abnormal state occurs or not is determined by using the remaining RRI values. A wearable device therefor is also provided.
Claims13
A physiological data detection method, comprising:
- detecting an electrocardiography (ECG) signal;
- detecting a photoplethysmography (PPG) signal;
- calculating a plurality of R-R interval (RRI) values according to the ECG signal;
- calculating a plurality of peak-peak interval (PPI) values according to the PPG signal;
- excluding wrong RRI values according to the RRI values and/or the PPI values;
- and
- determining whether a difference value between two adjacent RRI values in the remaining RRI values is greater than a preset value or not, and when the difference value is greater than the preset value, determining that an abnormal state occurs.
A wearable device for physiological data detection, comprising:
- an ECG detection module, configured to detect an ECG signal;
- a PPG detection module, configured to detect a PPG signal;
- and
- a calculation unit, electrically connected to the ECG detection module and the PPG detection module, and configured to:
- calculate a plurality of RRI values according to the ECG signal, and calculate a plurality of PPI values according to the PPG signal;
- exclude wrong RRI values according to the RRI values and/or the PPI values;
- and
- determine whether a difference value between two adjacent RRI values in the remaining RRI values is greater than a preset value or not, and when the difference value is greater than the preset value, determine that an abnormal state occurs.
