Abstract

Disclosed is a spontaneous exercise electrocardiogram system, adapted to synchronously record and analyze a user to obtain a spontaneous exercise electrocardiogram. The system comprises a electrocardiogram device and a analyzing computer. The electrocardiogram device comprises: an electrocardiogram sensor and a 3-dimensional acceleration sensor for detecting the user'"'"'s electrocardiogram signals and acceleration signals, respectively. Upon the analyzing computer receives the information from the electrocardiogram device, an indicator of physical activity (PA) or new physical activity (NPA) can be determined. After the heart rate of electrocardiogram and heart rate variability being matched and analyzed, the user'"'"'s spontaneous exercise electrocardiogram can be established.

Claims

3. The spontaneous exercise electrocardiogram system as claimed in claim 1, wherein the electrocardiogram device further comprises a wireless transmission module adapted to transmit the signal of electrocardiogram sensor and 3-dimensional acceleration sensor to the analyzing computer.

4. The spontaneous exercise electrocardiogram system as claimed in claim 1, wherein the physical indicator is a PA (physical activity), NPA (new physical activity) or an indicator derived from the acceleration signal of the user.

5. The spontaneous exercise electrocardiogram system as claimed in claim 1, wherein the cardiac abnormality comprises abnormal PQRST waves, heart rate and heart rate variability of electrocardiogram.

6. The spontaneous exercise electrocardiogram system as claimed in claim 1, wherein the instantaneous physical indicator of the user is automatically obtained by the analyzing computer and matched with the instantaneous electrocardiogram.

7. The spontaneous exercise electrocardiogram system as claimed in claim 1, wherein the components of x-axis, y-axis and z-axis at each time-point of the user is sensed and cumulated to obtain the total acceleration value for each time-point, and the total acceleration value is calculated to obtain its root mean square (RMS) of acceleration variation to be the acceleration variation of the user.
