As information communication technology developed we could check our blood pressure, pulsation, electrocardiogram, saturation of arterial oxygen (Sa02) and serologic chemical tests easily at home. It is possible though interlocking the house medical instrument with the wireless public data network. Data from patients can be transmitted to the distant hospital and will be essentially applied through wireless public data network. In this study we measured electrocardiogram (ECG) for the telemetry. We put the EGG function into the movable device and add 900MHz band wireless public data interface, through which patients could record EGG and keep the data at home. We used wireless network modem and NCL (Native Gontrol Language) protocol to contact through wireless network, and 8CR (Standard Context Routing) protocol in the networkto connect to the wired host computer. The host computer checks the recorded individual EGG data and then sends the correspondant reply to the movable device. The study suggests the medical transmit system model utilized by the wireless public data network. The suggestion in the study of telemetry system provides movement and preservation. And it will exam the health condition in distance or at home.
