Electrocardiogram production is one of the most reliable and most widely used tests for detecting heart problems and evaluating the heart’s health. Although it is traditionally performed by ECG machines at medical institutions, most recent developments in electrocardiography enabled even small mobile devices to perform this measurement. At the Neuronica Laboratory at Polytechnic of Turin, a group of experts developed PulsECG, an electronic wristband capable of acquiring an electrocardiogram and transmitting the digital data to a mobile application for analysis. The goal of this thesis was to design and develop a desktop application where the electrocardiogram data from PulsECG can be displayed and analyzed.
