The invention discloses a health management service system and method based on dynamic monitoring and analysis of heart functions. The system includes a heart health service cloud platform, a connected heart function intelligent monitoring and early warning device, an intelligent mobile terminal and a management subsystem connected with a medical service institution information platform. The mechanical vibration of the heart is monitored in vitro by a portable intelligent wearable device, vibration information of the heart is obtained in real time and non-invasively, and with combination of digital processing, machine learning and artificial intelligence technology pattern recognition and intelligent diagnosis, the abnormal physical structure and pulse rhythm of the heart are found in theearly stage, such as valvular lesions, abnormal movement of heart wall, change of the ejection fraction of the heart, arrhythmia and the like. With combination of an early warning reporting system, the purposes of early warning and timely medical care for heart disease can be realized. The system has great significance for early warning and monitoring and contrast postoperative rehabilitation monitoring of serious arrhythmia, angina pectoris and acute myocardial infarction, daily monitoring of home-based elderly people and physical exercise people.
