When does the y descent in jugular venous pulse occur?

y descent in jugular venous pulse occurs with decline of right atrial pressure when the tricuspid valve opens. Slow y descent is seen tricuspid stenosis. Very prominent y descent or Friedreich’s sign occurs in constrictive pericarditis as the right ventricle is not able to expand well during ventricular diastole.
