The lack of hospitals and medical devices is one of the main characteristics of under developed countries. This paper proposes the development of a very low cost and low power consumption module that is used to record Electrocardiogram (ECG) signals at home or in hospital. The pre-amplification is done using the well known AD620. The other analog signal conditioners are the low pass and high pass filters, the right leg drive circuit and the AC voltage level adaptation. A microcontroller (PIC 18F2550) is used for analog to digital conversion and for all the digital processes of the system. The ECG data recorded can be stored into a SD (Secure Digital) memory card. Our module is powered by two 9 volts batteries and it can be connected to any modern terminal through USB port. We designed and implement software that manages this ECG recorder. A friendly user interface has also been elaborated for graphical plotting and displays. The user can set various functioning states of the module through a control panel. As ECG recording is non invasive, we carried on hundreds of tests and the results were all satisfactory.
