Question

if blood supply is reduced in a small area of through which the left bundle branch passed, predict the effect on a ventricular contractions

Answer 1

If the blood supply has been reduced in a specific but small area of the heart, through which the branch of the left bundle passes through, there will be a reduction in the conduction of the action potentials through that particular side of the heart. It may also block the conduction of the action potentials.

This will lead to reduced contractions on the left side of the heart. However, there will not be any changes in the contractions on the right side of the heart and it will carry on its functions normally.

Since the contractions of the left side of the heart have been reduced, there will be a decrease in the effectiveness towards pumping of the blood by the left ventricle.

Answer 2

The heart compensates by enlarging. This works for a while, then the heart pumps better. But the enlargement doesn't stop. Keeps getting larger. Then the pumping is worse.
