<p>The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition.</p>

<p>In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power. ZigBee uses in applications where low power consumption is important compared to high data rate. For industrial purposes, ZigBee is used in sensors and control unit technology. For medical treatment ZigBee can be used for patient monitoring.</p><p>The aim of this work is to investigate if it is possible to wireless transmit an ECG signal with ZigBee-technology.</p><p>The result shows that an ECG signal can be transmitted by using ZigBee. Since ZigBee is designed for low power consumption, the Zigbee-module must be set in passive mode in most of the time.</p>
