Miniature Wireless Measurement Node for ECG Signal Transmission in Home Area Network

A miniature wireless node for ECG measurements is presented. The ECG node is designed to be used in various applications including measurement of heart rate during physical exercise and continuous long term measurement of ECG for people assumed having, or being recovering from a cardiac disease. The ECG node is wirelessly connected to a computer using IEEE 802.15.4 based radio protocol. The device sends the measured ECG signal together with additional measurement parameters including battery voltage to the computer, where the ECG signal can be analyzed on-line. The ECG node can operate alone or it can be used as a part of an overall system being designed for monitoring people that are transferred from hospital to home treatment.
