Yes, when the AV valves open and blood begins to enter the ventricles they are in isotonic relaxation. This is why the pressure does not increase in the ventricles during this time.

Identify the phase of the cardiac cycle to each of the following systolic pressure and diastolic pressure?
Systolic Pressure occurs during ventricular ejection.Diastolic Pressure occurs during ventricular relaxation.
When does Isovolumetric relaxation and ventricular filling take place?
Ventricular Diastole
What heart valves are closed during systole?
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)
When preforming CPR what is known as the relaxation phase of the heart?
The relaxation phase of the heart is when there is no compression pressure on the heart.
What occurs during left ventricular relaxation?
open
What recoil helps keep blood flowing during ventricular relaxation?
The Elastic Arteries :)
The contraction of the ventricles is referred to as systole and the period of ventricular relaxation is called?
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Which phase of the cardiac cycle is longest?
ventricular diastole
Which phase of a muscle twitch is eliminated in complete tetanus?
relaxation phase
What portion of the cardiac cycle is shortened by this more rapid heart rate?
The ventricular relaxation period.
What is the term that defines the relaxation phase of the heartbeat?
diastole
The relaxation phase of the heartbeat is called?
Diastole
