This paper presents an acquisition system design integrated with commercial ICs and the Arduino DUE platform used for the development of a long-term ECG signal monitor. An efficient lossless ECG compression algorithm with a better Compression Ratio (CR) is employed to reduce a great amount of storage and transmission recording data. To fairly evaluate the performance of the proposed compression algorithm, all 48 ECG signals sourced from the MIT-BIH arrhythmia database are applied as the test patterns. The simulation results show CR averages of 2.66, which is similar to the recent Li et al.'s approach. In Addition, we successfully detect clear ECG signal from thumbs by using the proposed system with two electrodes. The experimental results clearly show that the proposed system would be a good choice for realizing ECG signal acquisition in the future.
