Fig. 95.— Transition pulse curves for Fisher, Hammond, Hartshorn, and Howland, Squad B, 



January 28, 1918. 



The curves show the changes in the duration of the pulse cycles at the transition from standing to 

 walking and also from walking to standing. X, transition point, standing-walking; 

 Y, transition point, walking-standing. Duration of pulse cycle is given in 0.01". Each 

 plotted point is the average of two cycles. The equivalent pulse-rate per minute is 

 shown at the right. The elapsed time is given in seconds in smaller type at the bottom. 

 The pulse-rates at the sixth, twelfth, and twenty-fourth minutes of walking are inserted 

 between the two transition curves and indicate the pulse-rates as the walking progressed.
