Solar ECG acquisition system

Cardiovascular (CVD) disease causes many people dying every year and these are sudden events hence can cause immediate death if not diagnosed early. Electrocardiogram (ECG) is the best available option today for diagnosis of heart and problems related to it. But conventional methods for ECG monitoring are based on line voltage so, it can contain noise and ECG signals are very sensitive to noise. It should be accurate for the diagnosis of the problems related to heart. Hence the system proposed here is based on solar power. The line voltage noise can be removed by this and the accuracy of signal increases. Today also there are many areas present in the world where electricity is not present. Such remote areas are not accessible for the advanced equipments like ECG monitoring device. Also, the tests with these equipments are so expensive, that poor people cannot afford it. Hence the system proposed here will provide the solution for this problem, that anyone can observe their own ECG. The system mainly consists of solar cell and batteries which provides the power to the acquisition system. The system output has been checked on digital CRO. It gives the ECG signal waveform. Testing of the system is done with digital CRO later the output can be provide to the mobile phone and further study of the ECG can be done with that. The initial stages of heart attack or heart problems can be detected with this and accordingly the help can be provided.
