Abstract: An FPGA-based system is presented here, capable of simultaneous measuring electrocardiogram (ECG) in-put values and display them in seven-segment displays, while it also derives a heart diagnosis, based on the above ECG. Heart diagnosis activates corresponding LED alarm system, providing information about several heart problems such as hypercalcemia, hypocalcemia, hyperkalemia, coronary ischemia, bundle-branch block and AV node block, all of them derived from critical time values of the ECG. Our system has also the ability of calculating and presenting in seven-segment displays, heart beat rate in pulses/min, with simultaneous activation of corresponding alarm system, which is responsible of lighting three respective heart beat rate LEDs, for vradycardia, normal heart beat rate and tachycardia. Additionally, buzzer alarm and all FPGA board LEDs are also simultaneously activated, if pulses/min values are less than 60 (vradycardia) or higher than 100 (tachycardia). The system uses DE10-Lite FPGA board with an HW 827 sensor connected to it. The above sensor output is also connected to a blinking LED system, in order to have visual information of heart beat rate. Our system can work with a variety of heart pulse sensors and it is clear that deriving a successful heart diagnosis requires an electrocardiogram recording that is as accurate as possible. The system can also be combined with IoT technology, offering doctors the ability to remotely monitor patients online.
