"WebThe filling pattern is divided into three phases: a dominant systolic phase, a diastolic phase, and a third short atrial contraction phase with small reversal (upstream) flow from the RA into the systemic veins. During diastole the tricuspid valve opens, and blood from the RA is drained into the RV in two phases, early and late diastolic filling. " - Duration of systole and diastole
