Suggest why an artificial pacemaker can be used to treat AF.

An artificial pacemaker would generate regular electrical impulses in the atria.

The regular electical impulses from the pacemaker are stronger than the irregular impulses from the SAN, therefore the ventricles would recieve regular electrical stimulation.

This would normalise their contraction and ensure effective cardiac output at a regular rate.

Explain how voltage-gated sodium ion channels on the membranes of neurones generate an action potential.

People with AF often also have narrowing of the valve between the left atrium and the left ventricle. This causes the wall of the left atrium to become thicker. Suggest why.
