Development of Portable Cardiograph Using Novel Front-End Solutions

In this paper, we propose a structure of a portable cardiograph. Contents and functions of all blocks are overviewed. We describe two main structures of portable cardiographs, prepare a comparative table of characteristics for different analog front-ends. All individual features of the chips are listed as well. We register a test signal and try to improve its quality by means of digital filtration, taking the signal gained from certified Biopack equipment as a reference. We calculate device power consumption to compute required battery volume. Finally, energy efficient preprocessing algorithm is proposed.
