Abstract: The square waves and pulses with obvious porter characteristics are inserted into each different adjacent existing dynamic electrocardiogram data to solve the time-consuming problem in the currently used manual input verification method. The standard database files are converted into analog siginals, then output automatically to the ECG acquisition device according to the sequence of the database files in one time. The data recorded in the acquisition equipment is separated according to the interval data protocol, so as to achieve the purpose of rapid digital examination of dynamic electrocardiogram.
