a 
pause can regulate an alternation to the normal rhythm with equally 
high systoles. When a heart pulgates in alternation, I apply an 
extra-stimulation to the auricle or to the basis of the ventricle at 
the end of the diastole (Fig. 9). We can then obtain an extra-pause 
without extra-systole of the ventricle. This extra-pause is then followed 
by systoles of the ventricle, which obtain an equal height. In this 
way in Fig. 9 at 1 an extra-stimulation was applied to the basis
