During isovolumetric phases of the cardiac cycle, the atria are contracting.
<h3>What happen in isovolumetric phases of the cardiac cycle?</h3>
The isovolumetric contraction occurs in isovolumetric phase that causes left ventricular pressure to rise above atrial pressure. This leads to opening of aortic valve at the end of isovolumetric contraction when left ventricular pressure exceeds aortic pressure.
So we can conclude that during isovolumetric phases of the cardiac cycle, the atria are contracting.
