D-Heart biomedical start-up was founded in 2015 thanks to the work of Nicolò Briante and Niccolò Maurizi, at the time two young students in the interdisciplinary environment of the Almo Collegio Borromeo of Pavia. Maurizi is a young doctor researcher in cardiology at the University of Florence. When he was sixteen, Maurizi was hit by a myocardial infarction. He decided to became a doctor and transform his problem into an opportunity. Thanks to the help and business expertise of his roommate, Briante, they created D-Heart, the first smartphone ECG device that combines the usability required by the patient and reliability of the ECG wanted by the doctor.
