A portable and low-cost 12-lead ECG device for sustainable remote healthcare

The diagnosis of cardiac patients is commonly done using Electrocardiogram (ECG). But in the frequently used 3- Lead ECG device, all the cardiac diseases are not covered in the diagnosis. This paper illustrates an approach towards developing a 12-Lead ECG system. The existing 12-Lead ECG systems are costlier and require a large setup size. Also, these machines are not that user-friendly to be operated in rural areas. The proposed system is compact which makes it portable and shows effective results in ambulatory systems. This manifesto presents a customized approach towards designing an ECG amplifier, and Digital data converting and storing unit, enabling the domain of `Internet of Things' which makes it a very effective mode of Telemedicine. The received digital data is directly uploaded to an online database. To minimize the cost, reduction in hardware has been suggested without compromising on the quality of signal captured. Use of basic embedded and open source tools made the system simple and easy in terms of handling. This study has fostered a successful working model which helps in acquiring 12 ECG outputs altogether for a thorough diagnosis of cardiac patients.
