WebDec 29, 2024 · Ventricular systole refers to the period of contraction of the ventricles. The electrical impulse arrives at the atrioventricular node (AV node) shortly after the atria are depolarized. There is a small delay at the AV node, which allows the atria to complete contracting before the ventricles are depolarized. WebWhen pressure within the ventricles drops below pressure in both the pulmonary trunk and aorta, blood flows back toward the heart, producing the dicrotic notch (small dip) seen in blood pressure tracings.
