Wearable Wireless Sensors Node For Heart Activity Telemonitoring

The technological progress of wireless communication, embedded systems and health equipment offers innovative alternatives to medical care, in particular, the telemonitoring of vital signs such as the ECG signal for heart disease control. In this paper, a novel approach for the ECG telemonitoring based on a Wireless Sensor Node is proposed, where the ECG signal is measured with noise suppression. The acquired signal is used in QRS peaks detection to determine the heart rate. Thanks to a wireless transceiver the heart rate is transmitted in real-time to a base station, which is able to aggregate data via a Cloud on the IoT platform for heart rate telemonitoring in real-time. The experimental results show that the system is effective and reliable for the ECG measurement, processing, transmission, and visualization of information in real-time for the purposed remote monitoring of heart activity.
