Question

The end diastolic volume in a rapidly beating heart (hr about 170/min) will be reduced because

Answer 1

Because when the heartbeat is accelerated, the amount of blood ejected into the body becomes greater, decreasing the amount of blood inside the veins.

Step-by-step explanation:

Diastolic volume is the term used to describe the blood that is present in the ventricles after the diastole is performed. Distole is the period in which the heart enters a state of relaxation, right after the cardiac muscle contraction that allows blood to be expelled from the heart to the organism.

When a person's heartbeat is accelerating, a greater volume of blood is ejected into the body, causing the volume of blood inside the ventricles to be less. As a result, the final diastolic volume will be reduced.

Answer 2

The end diastolic volume in a rapidly beating heart after an hour about 170/min will be reduced because the heart rate/heart beat will be in calm beating whenever the patient is already relaxed and gain his breathing from the rapid heartbeat which is caused by running, using stairs or from exercising.
