In the near future, the Android systems [8,9] are expected to be more popular. From the perspective of health care applications, the Android system with wireless transmission in smart home also provides a feasible solution for the development of a portable ECG monitoring system. So, in this paper, we present the healthcare system model and application function, and make analysis of Arrhythmia classification based on RRI. For the experiments, MIT-BIH database [10] is adopted as the benchmark to test and verify our proposed method. The rest of this paper is organized as follows. In Section 2, the background information is about the ECG and classification algorithms. The personal healthcare system is introduced in Section 3. Then, the analysis of arrhythmia classification is shown in Section 4. Finally, Section 5 concludes with a short summary of the research contributions.
