Best Answer

Atrial refers to the top portion of the heart and diastole is when the heart is at rest. Atrial diastole would be when the top portion of the heart is not beating.

What is the time length for atrial diastole?

.7 seconds


What is your heart doing when it is in systole?

Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.


When is atrial and ventricle at rest together?

At diastole the muscles of the atria and ventricles relax and blood flows into the heart. Therefore the atria and ventricles and at rest together during diastole.


Is systolic pressure where the ventricls are relaxing?

Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole


Does the p wave in an ekg indicate atrial depolarization?

No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).


What is the stage of the cardiac cycle which precedes the resting period?

The stage of the cardiac cycle that precedes the resting period is known as diastole. During diastole, the heart relaxes and fills with blood before contracting again during systole.


What is a complete cycle of a heart contraction and relaxation called?

Cardiac cycle, which is made up of atrial and ventricular systole and diastole.


What controls the heart rate at rest?

The third apsect of the cardiac cycle is the rest period, however it is not separate from the sytole and diastole. It is merely the time frame during a cycle when both the artia and ventricles are in disastole at the same time. It thus can be said that the period of rest overlaps atrial and ventricular diastole.


What is the term that defines the relaxation phase of the heartbeat?

diastole


What happens to the volume of blood in the ventricle during the period of isovolumetric contraction?

Both ventricular contraction and atrial diastole take place.


What is the purpose of the auricle in the heart?

The Auricle increases the volume of the atrium.Right auricle collects the deoxygenated blood and pushes it to the right ventricle. Left auricle collects the oxygenated blood from lungs and pushes it towards left ventricle.


How is pulse related to systole and diastole?

Pulse is the rhythmic expansion and contraction of arteries caused by the heartbeat. Systole is the phase of the heartbeat when the heart contracts and pumps blood into the arteries, causing the pulse to be felt. Diastole is the phase when the heart relaxes and refills with blood, leading to a decrease in the pulse sensation.
