What is the significance of the time gap in the passage of action potential from sino-atrial node to the ventricle?

Open in App

Solution

Significance:

The time gap in the passage of action potential from the SA node to the ventricle gives the ventricle enough time to relax.

This results in a fall in ventricular pressure and allows the closing of semilunar valves.

This prevents the backflow of blood into the ventricles.
