1.3 Function and Speciality
The ECG workstation connects with matched software by means of Bluetooth, it can help doctors
to analyze, diagnose and print patients’ ECG. It can be used in ECG rooms, sickrooms and
community hospitals. The software's characteristics are as following:
1. The sampling template adopts real-time sampling, display and store mode, which is clear and
perspicuous. It not only has functions like real-time analyzing QRS wave, calculating heart rate
and real-time print, but also has three filtering methods: baseline filtering, frequency filtering,
2. Advanced arithmetic is adopted in the software, so that it is more perfect when the computer is
