Abstract :
The authors have developed a system which scans electrocardiogram (ECG) waveforms stored on paper and converts them to digital data stored on a computer. The system enables quick and reliable measurements of QT intervals, thereby replacing the tedious and potentially insensitive method of hand measurements. Preliminary results of comparison between hand and user-interactive measurements are presented to show the accuracy and characteristics of the system
