Why AV node called the pacesetter of heart
Dear student,
The atrioventricular node relays and intensifies the cardiac impulses. AV is known as pacesetter because it serves as an electrical relay station,slowing the electrical current sent by the sinoatrial node before the signal is permitted to pass down to the ventricle.
