Diseases of the circulatory system are among the chronic degenerative pathologies with the highest morbidity, representing one of the main causes of disability. The general definition of cardiovascular diseases (CVDs) includes all the diseases of the heart and blood vessels. These represent the first cause of access to first aid, as well as death. In order to contain the number of hospitalizations and healthcare costs, innovative prevention and monitoring techniques for patient’s health are needed. To date, conventional techniques to monitor the patient’s cardiovascular activity are intrusive and invasive. The main goal of this work is to overcome these limitations, by introducing the design of a non-invasive and non-intrusive system for heart rate (HR) detection.
