Abstract

A telemonitor for ECG was developed for regular monitoring, wireless and longrange transmission and signal processing of the electrical activity of the heart. The whole system was divided into three parts: a hardware sensor unit, a smart phonebased application, and a Windows- based application. The hardware sensor unit consists of an ECG shield, an analog-to-digital converter, and a Bluetooth shield to process and transmit data. It uses a sampling frequency of 32 Hz. The smartphone application is composed of the MACOPA (Mobile Aid for Cardio Out-Patients Application) that sends data through Short Message Service (SMS), and stores them in a local folder. It uses a base64 encoding system to double the initial capacity of a single SMS. The Windows-based application is composed of the MACOPA for Doctors that processes the data sent through SMS, displays them on the computer screen and saves into a database. Waveform properties of the signals from the heart were extracted and displayed on the screen. The study showed that the signals generated by the system are similar to the commercially available electrocardiogram making the medical practitioners give the same interpretation. The system is capable of transmitting ECG signals wirelessly in long range. Further improvements are still needed to make the system more reliable in monitoring of the electrical activity of the heart.
