A Smart Method for Detection and Research on Heart Sound

Objective: Based on the problem of aging population, increasing heart disease prevalence and the difficulty of seeing a doctor in hospital, the paper studies on the long-term continuous changes of heart sounds to implement real-time monitoring and remote diagnosis at home. Method: by use of wireless sensor technology, signal processing technology and network transmission technology, the paper designs a remote heart sound detection and analysis system based on internet of things. Results: this method can detect the heart sound, transmit the data and diagnose remotely on real-time. Conclusion: according to the patient information and heart rhythm index storage of hospital database, doctors can make the medical scheme in time to prevent and treat, which has a wide commercialization prospect.
