Year: 2026

Type: article

Abstract: The intelligent heart sound auscultation technology integrates electronic technology, signal processing technology, and artificial intelligence technology, opening up a new path for the diagnosis of heart diseases. This paper comprehensively reviews the development history, underlying principles, applications, current challenges, and future directions. Evolving from conventional stethoscopes, the technology leverages advanced sensors and algorithms to acquire, process, and analyze heart sound signals, demonstrating immense potential in healthcare. However, it still faces obstacles in technical implementation, clinical validation, and regulatory compliance. Moving forward, intelligent heart sound auscultation is poised to advance toward greater intelligence, multifunctional capabilities, and standardized frameworks, offering robust support for the diagnosis and treatment of cardiovascular disorders. • Intelligent heart sound tech lifts cardiovascular diagnosis accuracy vs stethoscopes. • It integrates electronic, signal processing & AI for non-invasive heart screening. • Key challenges: technical instability, insufficient validation, unclear regulations. • Future directions: higher intelligence, multifunctionality, standardized frameworks.
