Storing ECG waveforms in a digital format has been available for several years. Remarkably, the vast majority of ECG analysis remains performed on paper printouts. However, using ECGScan software makes it possible to convert an image of a scanned paper ECG into a digital format. Then you can export the now digitized ECG files in to AMPS XML or FDA HL7 XML formats.
Archival storage of ECG waveforms can be efficiently digitized thus avoiding the need to maintain large paper-based databases. With the use of ECGScan, paper ECG will be converted into true digital ECGs. The files then represent ECGs as if there were originally acquired in a digital format.
It must be noted that dependent on the layout of the paper ECG it may not be possible to derive Representative Beats (Median). To accommodate this limitation, the ECG annotations are placed on the Rhythm strip.
ECGScan can process ECG images with medium resolution (300 or 600 DPI are suggested), in grayscale and color, and stored in the major graphical formats, such as, JPG, GIF, TIFF and PNG.
The software can detect one lead at a time, but also simultaneous waveform detection based on predetermined model layout of paper ECG printouts (for example: 3x4 with long lead II at the bottom).
ECGScan allows the user to define an area of "Time Synchronization", an area on the image in which "time is preserved". ECGScan will automatically compute the Lead Offsets during the digitization.
Since January 2018 the licensing of ECGScan is restricted for specific purposes (research/academic and non-profit). For other uses please refer to the AMPS Paper ECG to Digital Service described here.
