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.

atrial diastole
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.
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.
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
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).
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
Systole is when a chamber of the heart (i.e. atrial vs. ventricular systole) is contracting. Diastole is when a chamber of the heart is relaxing. Without qualifying which chamber it is usually assumed to mean the left ventricle.Systole refers to when the heart is contracted and diastole refers to when the heart is relaxed.
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.
diastole
Both ventricular contraction and atrial diastole take place.
