ELECTRICAL STIMULATION OF THE FKOG'S HEART. 



Should stimulation cause an instantaneous auricular systole, 

 then the ventricular reduplication has a latency of nearly equal 

 value at all times at which it may occur, but should there be, 

 as in Fig. 211 Ej, a considerable auricular latency (about 1'') 

 then the ventricular latency is liable to great variations.
