Jugular venous distention develops in right-sided heart failure, constrictive pericarditis, pericardial tamponade, obstruction of superior vena cava. JVP normally falls with inspiration but may rise (Kussmaul sign) in constrictive pericarditis. Abnormalities in examination include:
- Large “a” wave: Tricuspid stenosis (TS), pulmonic stenosis (PS), atrioventricular (AV) dissociation (right atrium contracts against closed tricuspid valve)
- Absent “a” wave: Atrial fibrillation
- Large “v” wave: Tricuspid regurgitation, atrial septal defect
- Steep “y” descent: Constrictive pericarditis
- Slow “y” descent: TS
