| Abstract: | a long time contintiotis sampling and real-time analysis system for two chan-tiel ECG signals was realized on microcomputer.The problem of how to save a large numberof ECG data continuously was resolved by using the expanded memory. The system couldsample and save two channel ECG signals exceeded thirty minutes. Real-time sampling anddisplay were implemented by interrupt-routine.The system could display,analyse and clas-sify ECG signals at the same time and give an alarm when abnormal ECG signal occured.This system provided a good tool for the research of establishing ECG database and the clini-cal ECG monitor. |
