2. have QRS interval and ST segment calculating and writing function and a heart rate computing function, simple message diagnosis can be provided, uneven etc. as heart rate;

3. can directly be shown in computer screen through the RS232 transmission, and the wave recording data;

4. having simple and easy electrode and light and handy body can carry and can measure immediately;

5. but have external electrode connecting plug line and measure static state or ambulatory electrocardiogram;

6. the sphygomanometer function of having can be inflated and leak gas automatically measurement blood pressure and heart rate data and record automatically;

7. low-voltage detecting;

8. the operation mistake of having detecting and state show;

9. have a time clock feature.

This utility model ecg data memory capacity can reach 50 groups, is that a kind of simple to operate, easy to carry, measuring ability is complete and can be the measuring device that the doctor provides the reference treatment foundation.
