The Development Of Multi-function Portable Ecg Monitor

AB STRACT The author is engaged in the studying and manufacturing of an intelligent ,capable and portable,multifuctional electrocardio monitoring equipment with AduC8 12 Single-chip .Microcomputer.The equipment can gather and record the electrocardio signals automatically,also can analyse it at real time,and send it out to the monitoring center through the telephone at real time or send it out by serial interfaces to computer.It use the graph display device to show the electrocardio waves and menu.Cooperated with buttons,it provides amicable interface,and makes operation simple and convenient.Based on the feature of the electrocardio signals, this paper also proposes a electrocardio distortionless data compression algorithm.The algorithn is simple but effective,it can process the data at real time,and the compression-ratio reaches 2～6.
