What node triggers and impulse?
The sinoatrial node triggers an impulse
Is AV NODE known as pacemaker?

The sinoatrial node is the heart's?

What is the peacemaker of the myocardium?

What pacemaker of the heart initiates depolarization under normal conditions?
The primary pacemaker of the mammalian heart is the sino-atrial node. If the SA node fails, the atrioventricular node (AV node) takes over pacemaking.
Is sinoatrial node called a pacemaker?
yes
A heartbeat begins with an impulse from the?

What conducting cells set heart rate?
Sinoatrial Node (SA node)
Is the pacemaker of the heart under normal circumstances is called the sinoatrial SA node?
Yes the sinoatrial node is also called the pacemaker under all circumstances
What does the sinoatrial node do when body temperature is increased?
Known as the "pacemaker of the heart," the sinoatrial node would most likely speed up if the body temperature were to rise.
