The initial main purpose in this project was to design a portable prototype capable of monitor the electrocardiogram of a human person using three electrodes. This prototype would include the ADS1292R chip and its conditioning electronic circuit. It would transfer the data by wireless to a PC or mobile device. However, the main objective has not been fulfilled instead, it has been developed an interface using LabVIEW to monitor the electrocardiogram. The ADS1292R microcontroller is included in a shield to be used together with Arduino UNO. The communication between LabVIEW and Arduino is set up by Serial Port
