“An apparatus called a ‘pulse register’ has been devised by a
Viennese physician, Dr. Gartner. It is intended,” says _The
Medical Times_, “to watch and register the action of the
heart and pulse while the patient is under the influence of
chloroform, ether, or cocain. The apparatus consists of a
watch-like box, to be attached to the patient’s forearm. The box
has a graduated dial and hands, working according to pulse and
blood-pressure vibrations, which are registered by an elastic
spring in the most precise manner imaginable. The physician in
attendance, or operator, is all the time kept informed of the
exact degree of the unconscious person’s pulse and heart action.
The controller, furthermore, shows the action of pulses which
the physician’s fingers can not feel nor find.”
