I herewith attach the sphygmographic tracings made upon myself by another, showing the state of the pulse as compared with the progress of the respiration.
The sphygmograph may also be useful in the diagnosis of simulated disease, after the example set M. Voisin in the case of a sham epileptic in Paris, "whose sphygmographic lines have no resemblance to those of true epileptics before and after a fit, and only resemble those produced by normal persons after a violent gesticulation."
Thus the sphygmographic data on the circulation of the blood, which reveal the inner emotions, in spite of an outward appearance of calm or indifference, have already served to show that a person accused of theft was not guilty of it, but that he was on the contrary guilty of another theft, of which he had not been so much as suspected.
The heart, on the fifth and sixth days after alcohol was left off, and, apparently at the time when the last traces of alcohol were eliminated, showed in the sphygmographic tracing signs of unusual feebleness; and, perhaps, in consequence of this, when the brandy quickened the heart again, the tracings showed a more rapid contraction of the ventricles, but less power than in the alcoholic period.
In the sphygmographic tracing, the line of ascent is less abrupt than in the normal tracing (Fig. 2), and not nearly so high, and it is rounded at the top.
With this condition, the pulse is hard and incompressible, and the line of ascent in the sphygmographic tracing (Fig. 3) is higher than in health.
The beat on the fifth and sixth days after alcohol was left off, and apparently at the time when the last traces of alcohol were eliminated, showed, in the sphygmographic tracing, signs of unusual feebleness; and, perhaps, in consequence of this, when the brandy quickened the heart again, the tracing showed a more rapid contraction of the ventricles, but less power than in the alcoholic period.
"The first and very transient effect is generally increased frequency of beat, followed immediately by dilatation of the peripheral vessels from impaired vasomotor sensibility, and the same unsteady or wavy sphygmographic tracing as is given in typhoid fever, and which is usually regarded as evidence of cardiac debility.
