I am researching what is triggering the extrasystoles - initial idea from this thread about Which ionic channels of Pacemakers can work in very low frequencies in extrasystole? I am interested in the reflex arc with extrasystoles.

I am not completely sure if the intrinsic regulation of the heart can start specific stimuli. I have now intuition that not possible.

What are the reflex arcs of the heart?
