Steps of the proposed network of our system.

Step	Description
1	The ECG signal is generated from an ECG sensor connected to the patient.
2	The microcontroller receives the ECG signal and delivers it to a client process running on a local computer.
3	The client process starts a timer, transmits the ECG signal to the IoT-Blynk web platform, sends an SMTP message to the patient’s doctor, and moves to a waiting state.
4	The doctor receives a warning message and connects to the IoT-Blynk web platform to analyze the ECG signal.
5	The doctor, from a mobile application, generates a diagnosis and sends the alert message to the patient’s medical staff (the client process receives a copy of the message).
6	If after a predetermined time there is no alert message from the doctor, the client process sends a request to the intelligent system.
7	The intelligent system, using fuzzy logic, analyzes the ECG signal, generates a diagnosis, and sends the alert message to the patient’s medical staff.
8	In either case, the patient’s medical staff receives the alert message and takes the necessary medical actions to benefit the patient’s health.
