5600mls
6600mls
7600mls
8600mls

The spike phase of the action potential of the sinoatrial node pacemaker cells of the heart is caused by:
Opening of voltage-gated Na+ channels
Opening of voltage-gated Ca2+ channels

These cells are known as the primary pacemakers of the heart:
Fibers of the left and right bundle branches
Fibers of the bundle of His
Cells of the atrioventricular (AV) node
Cells of the sinoatrial (SA) node

4 X threshold
6 X threshold
8 X threshold

What is the best description of Eisenmenger’s syndrome?
It occurs when a right to left shunt becomes left to right due to a build-up of pressure on the left side of the heart.
An initial left to right shunt becomes right to left due to increased pulmonary blood flow and eventual right ventricular hypertrophy (RVH).
It is due to lack or aorticopulmonary septum formation.
It is due to failure of the aorticopulmonary septum to spiral.
