Part. I: PULSE-PRESSURE IN HEALTH, WITH SOME NOTES ON THE INFLUENCE OF CARDIO-VASCULAR DISEASE (1) Most boys examined (9 - I4 years) have a pulse-pressure of 40 - 45 m.m. of mercury. (2) Pulse-pressure of youths from 15 - 20 years is 40 - 50 m.m. (3) The age-group 21 - 30, shows pulse-pressure mostly between 46 m.m. and 50 m.m. (4) The age -group 31 - 40 tends to be 40 - 50 m.m. and above. (5) Men of 41 - 50 years have a pulse-pressure of 40 - 50 m.m. with a considerable number giving readings of 51 - 60 m.m. These latter are nearer 50 than 40 years of age. (6) In the age-group 51 - 60, pulse-pressure rises to 56 - 65 m.m. (7) The age of the subject plus 100 represents the maximum systolic pressure. (8) Pulse-pressure is increased by physical exercise; also by emotional states up to the age of 10 years. For the 10 years following, the diastolic pressure increases proportionally with the systolic under Emotion, and a pulse-pressure of about the normal results. After 50 years, the systolic pressure rises relatively higher than the diastolic, and the pulse-pressure once more increases. (9) In a not inconsiderable number of men, a full meal definitely increases pulse-pressure. The action of alcohol is uncertain in this respect. (I0) Pulse-pressure is unaltered, or even tends to increase in healthy men who are confined to bed for two or three weeks.
