The Strophanthus Pulse in Heart Disease.
—At the International Congress for Therapeutics and Materia Medica, Paris, 1889, Bucquoi demonstrated the strophanthus pulse by means of sphygmographic tracings obtained from fourteen patients after the administration of strophanthus. The curves show the following peculiarities: The up stroke is higher and steeper and the angle more acute; the pulse resembles the aortic pulse. The increased cardiac action drives the blood more rapidly into the vascular system; the up stroke therefore becomes higher and steeper. The pulse becomes stronger, the number of beats diminishes and the pulsations generally become more regular. Contrary to the views of the physiologists, Bucquoi holds that strophanthus is not an agent that acts directly upon the vasoconstrictors, and that therefore it may be employed with advantage in aortic defects. Upon the whole, the remedy acts immediately upon administration. It may be given for a long time without disadvantage, and
