4-Lead ECG Monitoring for Cardiac Care: Advancing Healthcare with Innovative Use of Connected Watches

nowadays, technological devices commonly known as "connected objects" are becoming increasingly integral to our daily lives, penetrating various domains. In the field of healthcare, for instance, the Internet of Things (IoT) has revolutionized the provision of medical services. With devices and sensors becoming increasingly "smart," they generate valuable data for healthcare providers, which is especially significant in cardiology. The utilization of IoT technology enhances the quality and efficiency of care while also reducing the time lag between the identification of abnormalities and medical intervention, this greatly simplifies the task of medical professionals and contributes to an overall improvement in health status. This article proposes a study that explores the diverse possibilities of utilizing a connected watch for monitoring electrocardiograms (ECGs) with one, two, three, or four leads, comparing these results with those obtained through an electrocardiograph or a conventional electrocardiograph in a clinical setting. Furthermore, it proposes a specific application of the connected watch for ECG monitoring in cardiology.
