The Design of ECG Signal Generator using PIC24F

This paper reports a precise design and development for ecg signal generator for testing and calibration of the electrocardiogram equipment, ecg signal processing system and heart teaching tool. It can create a guide II signal of time and profile features lead II signal across a range of ecg drawings of heart rate within 45 to 185 devices in the first device of steps. This can be set up 15 ∼ the QRS 45 years old lady with a lady who resolution. P, T wave amplitude can be adjusted from 1-100% to 1% of the total of the amplitude QRS complex resolution. A color LCD touch screen is able to provide the user with input parameters facilities, depending on the output waveform parameter and a graphical representation of the output waveform. Signal generator outputting signal of poor precision through digital simulation stage using low noise design provides accurate signal amplitude QRS the lower end of the technology range.
