Background
• Despite a technology that permits storage of
raw data in digital format since many years, a
vast majority of ECG analyses is still performed
on paper printouts, either directly on paper
copies or with the support of on-screen calipers
methods applied to the scanned printout
converted to a digital image format.
• This mode of operation has sometimes caused
some confusion in the terminology and in
particular on the definition of a “digital ECG”.
