In this paper the design of a Graphical User Interface (GUI) is proposed for healthcare applications. The GUI is designed in MATLAB environment and is specifically suitable for advanced phonocardiography (PCG). This diagnostic method is more and more important nowadays, due to the advances in signal processing methods and computer processors performances in order to detect with a simple PC based electronic stethoscope, pathologies otherwise detectable with much more expensive and time-consuming medical techniques and device
