Abstract:

A technic is described for displaying vectorcardiograms with greater precision and clarity than is possible with most methods in use. This is accomplished by using a magnetic recorder-reproducer for time-base expansion of recorded VCG data. With time expansion, recorded data appear to be lower in frequency and can be graphically displayed on an X-Y recorder. Illustrations showing the vectorcardiographic loops obtained are contrasted to a conventional recording technic. Author
