Abstract

An apparatus for recording physiological signal is provided. The apparatus includes a storage unit, a signal analyzer, and a controller. The storage unit is configured for storing a physiological signal of a user during a time interval. The signal analyzer is configured for analyzing the physiological signal of the user to provide an analysis result. The controller is configured for changing the time interval according to the analysis result.

Claims

1. An apparatus for recording a physiological signal, comprising:

a storage unit, configured for storing a physiological signal of a user during a time interval, wherein a quantity of the stored physiological signal is related to the time interval;

a signal analyzer, configured for analyzing the physiological signal of the user to provide an analysis result; and

a controller, configured for changing the time interval according to the analysis result, so as to change the quantity of the stored physiological signal.

2. The apparatus as claimed in claim 1, wherein the time interval is less than 60 seconds, and the controller changes the time interval by increasing the time interval more than 10%.

3. The apparatus as claimed in claim 1, wherein the time interval is changed by changing the start time of the time interval, changing the stop time of the time interval, or separating the time interval into a plurality of intervals.

4. The apparatus as claimed in claim 1, wherein the storage unit receives the physiological signal of the user from a physiological signal sensor through one of a wired connection and a wireless connection.

5. The apparatus as claimed in claim 1, wherein the physiological signal of the user is an electrocardiography (ECG) signal and the analysis result is indicative of one of whether the ECG signal is unreliable, whether the ECG signal is noisy, whether morphology of the ECG signal is abnormal, whether rhythm of the ECG signal is abnormal, and whether the ECG signal is normal.

6. The apparatus as claimed in claim 5, wherein the controller extends the time interval when the analysis result is indicative of the morphology of the ECG signal being abnormal or the ECG signal being unreliable.

7. The apparatus as claimed in claim 1, further comprising:

an input interface configured to receive input information,

wherein the input information comprises one of a health condition and a service request entered by the user.

8. The apparatus as claimed in claim 7, further comprising:

a wireless communication module configured to transmit one of the physiological signal of the user and the input information to a remote server or to establish a connection for an on-line service between remote server and the user.

9. The apparatus as claimed in claim 1, further comprising:

an output interface configured to generate one of a visual signal and an audio signal according to the analysis result.

10. The apparatus as claimed in claim 1, further comprising:

an output interface configured to generate one of a visual signal and an audio signal when the storing the physiological signal of the user is completed.

11. A method for recording physiological signal, comprising:

storing a physiological signal of a user during a time interval, wherein a quantity of the stored physiological signal is related to the time interval;

analyzing the physiological signal of the user to provide an analysis result; and

changing the time interval according to the analysis result, so as to change the quantity of the stored physiological signal.

12. The method as claimed in claim 11, wherein the time interval is less than 60 seconds and the time interval is changed by increasing the time interval more than 10%.

13. The method as claimed in claim 11, wherein the step of changing the time interval further comprises:

changing the start time of the time interval;

changing the stop time of the time interval;

or

separating the time interval into a plurality of intervals.

14. The method as claimed in claim 11, wherein the physiological signal of the user is received from a physiological signal sensor through one of a wired connection or a wireless connection.

15. The method as claimed in claim 11, wherein the physiological signal of the user is an electrocardiography (ECG) signal and the analysis result is indicative of one of whether the ECG signal is unreliable, whether the ECG signal is noisy, whether morphology of the ECG signal is abnormal, whether rhythm of the ECG signal is abnormal, and whether the ECG signal is normal.

16. The method as claimed in claim 11, wherein the time interval is extended when the analysis result is indicative of the morphology of the ECG signal being abnormal or the ECG signal being unreliable.

17. The method as claimed in claim 11, further comprising:

transmitting the physiological signal of the user to a remote server.

18. The method as claimed in claim 17, further comprising:

establishing an on-line service between the remote server and the user.

19. The method as claimed in claim 11, further comprising:

generating one of a visual signal and an audio signal according to the analysis result.

20. The method as claimed in claim 11, further comprising:

generating one of a visual signal and an audio signal when the storing the physiological signal of the user is completed.
