At present there are various measuring devices or instruments that acquire the electrical activity of the heart (ECGs), but make a proper measurement, models the signs are printed directly on sheets of graph paper, unable to save the information for later analysis. In this work we make the development of a bioelectric signal acquisition, in this case focused on the signals emitted by the heart to be acquired and stored on a computer. The system is based on a card bioelectric signal acquisition developed in the Maestria en Ciencias de la Electrónica de la Facultad de Ciencias de la Electronica en la BUAP called MIOCARD 1.0 [1]. This card has already implemented a 2-channel electromyograph, and this paper focuses on describing the design of a electrocardiography for the acquisition of the 12 signals that can be obtained from the heart. The card is based on a brand ALTERA FPGA family CycloneII (EP2C8Q208C7) and communication to and from the computer via the protocol is PCI (Peripheral Component Interconnect).
