Without a plateau extending the refractory period in cardiac muscles sarcomeres might be stimulated so quickly that they would contract and not relax and instead would experience a sustained contraction also called:

1) depolarization
2) Tetany
3) relaxation
4) repolarization

Respuesta :

Answer:

Tetany

Explanation

The refractory period in the heart refers to the shortest interval between consecutive contraction conducted impulses out of the cardiac muscle.

It is important because it allows adjustments to stimuli and limits amount of action potential sent per minute.

Without a plateau extending the refractory period in the cardiac muscles.

Sarcomeres might be stimulated to contract instead of relaxing leading to sustained contraction also called Tetany.

Tetany is an involuntary muscle cramp or contraction caused by overly stimulated nerves.
