FIG. -27 



The relatively modest effect on ventricular dynamics 

 recorded by Gotten & Moran (29) with a right 

 ventricular strain gauge arch would not appear to be 

 compatible with the present data. A simple means of 

 relating the experiments described above to the 

 studies of Charlier (26) is not immediately apparent. 



B. Carotido-Alfial Reflexes 



THE CAROTiDO-VAGO-ATRiAL REFLEX. In experiments 

 on this reflex the sympathetic chain from the stellate 

 ganglion down tiirough T-5 is removed intact on both 

 sides. This is done so that anv change in the atrial 

 "a" wa\e which occurs can be attributed to reflex
