Sinoatrial node part of the autonomic nervous system adjusts the heart rate and the arteriole diameter to regulate blood pressure through negative feedback
The SA (sinoatrial) node is generates an electrical signal that can causes the upper heart of the chambers (atria) to contract. The signal and then passes through the AV (atrioventricular) node to the lower of the heart chambers (ventricles), causing them to contract, or to pump. The SA node is considered the pacemaker of heart.
The sinus node continuously generates electrical impulses, thereby setting the normal rhythm and also rate in a healthy heart. Hence, the SA node is also referred to as the natural pacemaker of the heart

Answer:
Speed meaning momentum I would think you mean. And an inanimate concept of development gathers no momentum. I think you are asking how some team of people working on a development, gather momentum with their effort? Which of course depends on the team & the discipline of the effort. A team trying to gain momentum with their project in medicine would be very difficult indeed. Too many safeguards in place to stop momentum. Some new website concept might be hard to restrain it’s momentum. So since the question is so general & open ended, it is almost unanswerable. Being in the single category ‘Speed’ seems to deal with physics. I still believe the question is about the human construct ‘project development’ rather than physics.
