Resumen
The expansion of the concept of the Internet of Things (IoT), together with wireless sensor networks, has given rise to a wide range of IoT applications. This paper presents and describes the concept, theory of operation, and practical results of a Telecare-ECG (Electrocardiogram) Monitoring device, designed for the remote monitoring of out-of-hospital cardiac patients. ECG monitoring using the Telecare-ECG Monitor system ensures a better quality of life for patients and greater possibilities for the real-time monitoring and signaling of sporadic cardiac events, by recording instantaneous cardiac arrhythmias captured during certain activities or in the daily environment of the patient; furthermore, hospital resources are less impacted by this device than other devices. In accordance with the novelty and contribution of this paper to the field of ECG investigations, the results obtained in the analysis, testing, and validation of the Telecare-ECG Monitor system refer to the optimization of the functionality of the mobile ECG device under conditions that were as similar to reality as possible.
