WebThe network vs. pacemaker theory of the activity of RVL presympathetic neurons-a comparison with another putative pacemaker system john lin 2002, Autonomic Neuroscience WebApr 7, 2024 · A pacemaker is implanted in the body and continually monitors the heart's intrinsic, natural electrical conduction. It will deliver an electrical impulse to the heart if it detects that the signals are not being sent at the appropriate intervals. Typically, pacemakers are set to prevent a heart rate below 60 beats per minute.
