During this period, an increase in cardiovascular diseases has been observed, attributed to factors such as changes in dietary habits, physical inactivity due to staying at home, increased consumption of frozen processed food, psychological stress, lack of social interaction, and consequently, rising alcohol and tobacco consumption. This has led to a significant increase in cardiologists' workload and a shift from traditional technologies to remote patient monitoring models.In this context, remote Electrocardiogram (ECG) monitoring-based approaches have become widely used in recent years for the detection of heart diseases, owing to their reliability and non-invasive nature.This study introduces an SMTP-based tele-monitoring approach that facilitates remote monitoring of ECG signals and supports a medical simulator, aiming to alleviate the workload of healthcare professionals. The primary objective of this research is to develop a wireless monitoring framework for ECG signals, aiming to enhance patient monitoring and safety, reduce the workload of healthcare providers, and ensure equitable access to healthcare services. Our research focuses on implementing a portable, real-time, and cost-effective ECG monitoring system.
