Our purpose is to offer a means of arriving at an early and more definite knowledge of cardiac incompetency by calling attention to certain well marked pulsations in the peripheral veins. These are especially pronounced in the median basilic vein of the forearm and in the veins on the dorsum of the hands, and they occurred in all of a series of more than fifty cases in which a diagnosis of cardiac failure and tricuspid insufficiency had been made on other clinical and anatomic grounds. A large number of compensated controls did not show these pulsations.
The relatively common occurrence of functional tricuspid insufficiency is not recognized by clinicians in general as often as it should be. This has been pointed out frequently by Mackenzie.1 This fact was brought home to us when it was discovered that quite a large proportion of the average run of patients at our disposal
