Teachings of the Sphygmograph in General Paralysis of the Insane

Extract

The pulse-tracing in general paralysis has never been thoroughly investigated, and although the tracing said to be characteristic of this affection has been figured and described in several works, I have looked in vain for those records of the amount of arterial tension as estimated by the pressure gauge, without which a mere pulse-tracing is of little reliance and value. I have therefore endeavoured to supply in part this want by a detailed account of the sphygmograms taken in about forty cases of general paralysis, with records of tension measurement and occlusion pressure, the latter taken by Dr. Handfield Jones' sphygmometer, which registers a pressure of 20 up to 600 grammes. The tracings have been all taken, by means of a very perfect sphygmograph, upon smoked enamelled paper, and every source of fallacy which could possibly be eliminated was very carefully excluded.
