Question

The pacemaker of the heart generates how many impulses per minute under the normal physiological conditions in humans?​

Answer 1

Answer:

Since the SA node is the pacemaker, it reaches threshold faster than any other component of the conduction system. It will initiate the impulses spreading to the other conducting cells. The SA node, without nervous or endocrine control, would initiate a heart impulse approximately 80–100 times per minute.
