At first the pulse-curves have the char-acteristic signs of diminished tension, viz., a higher and more distinctdicrotic wave; then the tension can, by nervous influences, be in-creased, just as in Fig. 64, where C and R are tracings taken from the 150 INFLUENCE OF RESPIRATORY MOVEMENTS ON PULSE-CURVE. carotid and radial arteries respectively, during Miillers experiment,in which the dicrotic waves, r, r, indicate the diminished tension in thevessels.
