Abstract

The employment of plate cameras with gravity propulsion of the plate across the lens has persisted for routine clinical electrocardiographic work in the majority of laboratories which are also equipped with motor driven cameras. The necessity for the latter in research work, and in certain cases with abnormalities occurring rarely or with prolonged periodicity, is not denied.

The reasons apparent for this routine use of plates are:

  1. Convenience of filing, such as in the boxes in which the plates are sold, for permanent records from which prints may be made as desired.

  2. Assemblage of the three leads in a compact arrangement for comparative interpretation without the effort of cutting, trimming and mounting each lead separately.

  3. Greater facility of developing and printing small records, rather than long strips.

Three unfavorable factors in the use of plates, which are obviated in the use of cut photographic film, are noted, namely:

  1. Danger of
