Digital Phonocardiography for Predicting Heart Diseases: An Embedded System Approach

Resumen

Cardiovascular disease is a major cause of death throughout the world, particularly in resource-poor countries and developing countries, where windows of early detection are narrow. The Digital Phonocardiography (PCG) of this work is a low-cost, portable biomedical system for immediate identification and ongoing monitoring of cardiac pathology. Equipped with a digital stethoscope, an OLED display, and Bluetooth, the system uses embedded C programming techniques to analyze cardiac sounds and provide immediate diagnostic feedback. Due to its low cost and improved accessibility, the device is designed to enable early diagnosis and timely intervention, especially in healthcare environments that are resource-poor.
