CardiaQloud: A Remote ECG Monitoring System Using Cloud Services for eHealth and mHealth Applications

Cardiovascular diseases are the leading cause of death around the world. It is estimated that 17.7 million people die each year from such health conditions. The World Health Organization promotes the development of specific strategies to reduce the mortality rate due to cardiovascular diseases. This paper proposes an ECG monitor and its implementation using three approaches: hardware, software, and cloud services. For the hardware approach, we used an e-Health platform for Arduino with three leads. However, the software- and cloud-based approaches were implemented using the NodeJS framework to create the network communication between a local server and a remote server hosted on the Amazon Web Services infrastructure. Additionally, a responsive web application was developed to display the ECG signal, its R-R intervals, and the heart rate. Finally, an assessment was conducted to measure the quality of the ECG signal using Dynamic Time Warping.
