Design and implementation of remote ECG monitoring system-server program / 医疗卫生装备

ABSTRACT

Objective To build a server to receive ECG data from the smart phone through remote network transmission,which has the functions of data storage,painting ECG waveform at real time,browsing historical waveform,preliminary ECG self-diagnosis and etc.Methods The development was executed with C# language in Visual Studio 2013,which used the socket for network transmission,GDI for waveform painting,Dataset/Datareader for data access as well as thread for multithreaded programming etc.Five-point smoothing filter was applied to ECG signal preliminary processing,and classical difference threshold algorithm was used to implement waveform analysis of ECG data.The main QRS waves were detected,and ECG features such as R-R interval were analyzed to form ECG self-diagnosis report.Results The server received and showed the ECG data transmitted by smart phone successfully,and then generated ECG waveform and self-diagnosis report.Conclusion This server has a great performance on receiving the data from portable facilities.In addition,it also performs well and stably in accessing and showing ECG data.
