    underlying condition. If, now, such a pulse suddenly becomes irregular in force and rhythm, it may be considered that the nervous and muscular mechanism of the heart are wearing themselves out under the strain—that is to say, that the heart is going to pieces. Irregular pulse occurs in shock, hemorrhage, and overwhelming septic intoxication or other forms of toxemia, such as thyrotoxicosis. The volume of the pulse represents the quantity of blood which DitifTioais ] o^T op MOMTH, ^ 1 3 T t 1 0 '7 o^v or 1 t b 7 lO // /a /3 /y IS It, n (* ti tl 11 Tl MF I r 4 b. « r » r *1 i^r t C <«. i * <ta c A <a: <a r r <a hi :s 1- <t tr la a. z 10?' 106' IOJ-* lot' ICj' 101' toi' '1'r 0/ %' ISC I3c no 110 ICC 90 80 70 60 so fJ to is 30 2S 20 IS 10 g B 0 5 Tt -g O ft o 4 A -A -r !^ i i / M i ? -sf u (/> -i a 1/i 2 O \~ < cr a.

The volume is small after loss of blood from hemorrhage and in conditions where the systemic tissues have been depleted of fluids from any cause. Thus, volume decreases with increasing hemorrhage or progressing septic infections. Volume is closely associated with tension. Tension represents the pressure within the artery; it expresses the degree of blood-pressure. It is measured by the amount of compression which must be exerted to
