A wireless sensor network based on zigbee for ECG monitoring system

This paper describes the development of a remote monitoring system for ECG signals. Electrical activities obtained from the body are of great help both in the diagnosis of the disease and the follow of the patient. A ZigBee based wireless network via a device integrated into the belt is used to transmit the signals to the system. Thus, analog signal is measured with the multichannel ADC unit of the MSP430F2274 processors; this information is transferred to a device with a USB port by using ZigBee network and finally observation and storing are carried out by being converted to a PC. With this system, signals obtained from the patients can be monitored simultaneously.
