Our clinical experiments demonstrate conclusively, we believe, 

 that in the pulse-rate and blood-pressure reactions to graduated 

 work we possess a valid test of the heart's functional capacity. 

 If the systolic blood-pressure reaches its greatest height not im- 

 mediately after work but from 30 to 120 seconds later, or if the 

 pressure immediately after work is lower than the original level, 

 that work, whatever its amount, has overtaxed the heart's func- 

 tional capacity, and may be taken as an accurate measure of the 

 heart's efficiency. 



Method of Performing Our Test of the Heart's Functional 



The apparatus used consists of pairs of 5, 10, 15 and 20 pound 

 dumb-bells, and a steel bar about 40 inches long weighing 25 

 pounds. Two types of movements are done with the bells. 1 In 

 the first a pair of dumb-bells is held at the shoulder, one in each 

 hand and then pushed alternately above the head and toward 

 the median line until the arms are fully extended. As one bell 

 moves up fairly rapidly the other bell returns to the shoulder, 

 the two moving in a sort of see-saw rhythm. In the other move- 

 ment a bell is held in each hand, the arms hanging by the side of and 

 close to the body, and then each forearm is alternately flexed, 

 raising the bell to the shoulder. The patient stands or sits ac- 

 cording to his condition. But one movement is performed with 

 the steel bar. It is picked up from the floor with both hands 

 raised first to a level with the shoulder then pushed above the head 

 until the arms are fully extended and then quickly lowered to the 

 floor again with a single rapid motion. 



It is possible to calculate approximately the number of foot- 



Capacity. 



1 These movements were first described to us by Dr. Jacob Teschner, of New 

 York.
