| Abstract: | The article introduces the portable ECG monitoring system based on digital signal processor TMS320F2812. The ECG acquisition circuit achieves amplification and filtering of the original ECG signal. The signal processing circuit is designed using modular design method. It realizes data storage, human-computer interaction, serial communications and other functions. Additional function of real-time temperature display, makes the system more user-friendly. The ECG analysis system includes digital filtering with Matlab, real-time QRS wave recognition algorithm of adaptive threshold and adaptive template method for initial diagnosis of arrhythmia. |
