RESUMEN
Objective To develop a PDA-based wireless electrocardiographic monitoring system meeting the requirements of doctors in mobile work.Methods ECG signals were received from hospital monitor center through mobile network,and then were analyzed with digital signal processing technology and electrocardiographic information processing technology.The results were sent to patients as soon as the data were diagnosed by doctors,thus realizing the real-time monitoring.Results PDA-based wireless electrocardiographic monitoring system applied many advanced technologies such as mobile communication technology,blue-tooth technology,embedded database technology,etc.so that doctors could examine patients' records and electrocardiogram at any place and in any time.Conclusion Clinical experimental results show that the system fulfils doctors' requirements and improves their work greatly.
