Rational hydrotherapy : a manual of the physiological and therapeutic effects of hydriatic procedures, and the technique of their application in the treatment of disease . 0m iiiiiiiiK;---iiiiiiv. Fig. 19 (a). HOT SPOTS (p. 69). Fig. 19 (b). COLD SPOTS (p. 69), ANATOMY AND PHYSIOLOGY IN RELATION TO HYDROTHERAPY. 61 of the instrument. The three points of importance to beobserved in the curve are the primary, the tidal, and thedicrotic waves. The primary zuave marks the expansion of the artery 82under the impulse of the wave of blood from the heart. Itmeasures in a general way the force and amplitude of the car-diac impulse; the tidal luave, extending from the apex to theaortic notch, represents the sustained propulsion of theblood resulting from the energy stored up in stretching thearteries. As the stretched arteries contract, the pressure ortension is more or less maintained, according to the degreeof elasticity in the vessel walls. With a rigid, atheromatousartery, the pressure quickly falls. The rigid arteries of old age produce a marked but short 83tidal wave, followed by a very marked fall (Fig. 9). In aorticregurgitation, the fall is equally marked (water-hammer pulse)bec
