Abstract
In the preceding report1which deals with pulsus paradoxus as observed in the clinic, it was pointed out that this pulse is of some diagnostic value, provided it is properly interpreted. Pulsus paradoxus was defined as a rhythmic pulse occurring in natural breathing which shows a waxing and waning in size during respiration, evident on palpation in all the accessible arteries. A classification of pulsus paradoxus was given, and emphasis was laid on its occurrence in large pericardial effusions. In the course of the foregoing study, several questions arose which could not be satisfactorily answered by the clinical data. For instance, we were unable to determine which circulatory changes are responsible for the pulse phenomenon, and we were certain neither of the factors involved nor of how such alterations in circulation take place. Experimental studies of pulsus paradoxus are conspicuously few. In a careful review of the literature, only threeThis publication has 0 references indexed in Scilit:
