| Abstract: | This paper describes the development of a portable multi-function ECG signal generator,which is based on micro-controller.It uses technique of LCD screen,and realizes man-machine interaction by keyboard.In constructing and disposing data module of the ECG signal,Eigen-heartbeat Code mapping method gets ROM saved greatly.Therefore it can generate all kinds of user-defined ECG signal sequence with no extension of on-board memory chips.This system can also simulate kinds of ECG signals,which have various heart rates and symptoms.It can meet the needs of researching and maintenance of kinds of ECG instruments. |
