Abstract
The present invention provides a smart phone based ECG early warning system. The method solves problems that most of conventional ECG signal analysis programs have the defect of dependance on a server side and an ECG client cannot carry out early warning in real time; and meanwhile, a synchronous acquisition acceleration signal is added to provide motion and posture information for accurate analysis of an ECG signal. The system comprises a signal acquisition front-end, a bluetooth data transmission, an ECG storage and an analysis system on an android system, a back-end server system and an early warning system, and has the advantages of high real-time performance, high capacity, small volume and good interactive interface. The ECG signal is collected in 24 hours and cardiac diagnostic information is given to a doctor and a user for reference. When a heart is not abnormal, an alarm notice is given and functions of remote consultation and emergency are provided, thereby ensuring personal safety.
