Real-time monitoring of ubiquitous wearable ECG sensor node for healthcare application

Abstract

Wireless technologies and sensors network give new possibilities for monitoring of vital parameters with wearable biomedical sensors and allow patients the freedom to be mobile and still be under continuously monitoring and thereby provide better healthcare services. In this paper, a new concept for wireless and ubiquitous wearable belt-type ECG sensor node transmitting signal via an ultra low power consumption wireless data communications unit to personal computer using Zigbee-compatible wireless sensor node. ECG signal is detected using ECG receiver sensor node. An ECG Monitoring Program is implemented at the end user. The measured ECG signals carry a lot of clinical information for a cardiologist especially the R-peak detection in ECG. Variable threshold method is used to detect the R-peak which is more accurate and efficient compare to fixed threshold value. For evaluate the performance analysis, R-peak detection using MIT-BIH databases and long term real-time ECG is performed in this research. © 2009 Springer Berlin Heidelberg.
