Patent ID: 8209000

Claim:
An device for sensing a physiological signal comprises: two sensing units connected to two palms of a subject respectively for receiving a first electrocardiogram (ECG) signal; a filter for generating a second ECG signal by filtering the first ECG signal; an amplifying unit for generating a third ECG signal by amplifying the second ECG signal; an Analog to Digital converting unit for converting the third ECG signal into a digital signal; an operating unit for generating a plurality of analysis data by operational analyzing the digital signal, comprising: a QRS wave sieving unit for sieving a plurality of consecutive QRS waves from the digital signal, a heart beat measurement unit for generating a heartbeat cycle signal according to the QRS waves, a time-domain analysis unit for generating a time-domain analysis data according to the heartbeat cycle signal, a Fourier analysis unit for generating a Fourier analysis data, according to the heartbeat cycle signal, a PQRST wave sieving unit for sieving a plurality consecutive PQRST waves from the digital signal; and a PQRST wave analysis unit for generating a ECG analysis data according to the PQRST waves; and a display unit for displaying the plurality of analysis data.
