WebSystole occurs between mitral valve closure and aortic valve closure. On ECG, the R-wave apex coincides with the onset of systole, and diastole starts at the end of the T wave. What is atrial diastole? Atrial diastole: lasting about 0.7 seconds – relaxation of the atria, during which the atria fill with blood from the large veins (the vena cavae). WebThe atria pump blood into the ventricles and then the ventricles pump blood out of the heart. Chambers of the heart fill with blood during a relaxation phase ( diastole ) and eject blood during a contraction phase ( systole ). Atrial systole precedes ventricular systole.
