| Abstract: | To develop a portable multi-patient wireless telemetry ECG monitor with low cost and high performance,which was preferable for small and medium hospitals.The high integration of wireless module,with PTR 5000 was used to reduce the volume and cost.The number of patients monitored were easily extended with the application of USB.A new feature point recognition algorithm-ZNFD(zero neighborhood of first-order derivative,ZNFD) was applied to real-time ECG wave.Result show that this monitor with low cost and low power consumption can monitor 1 to 4 patients.Wave can be displayed continuously and ECG parameters are calculated automatically.Besides,ten types of arrhythmia can be detected. |
