Jugular venous pressure waveforms in various kinds of heart disease. In right ventricular failure, mean jugular venous pressure is elevated, but the
waveforms remain relatively unchanged. If right ventricular failure is accompanied by tricuspid regurgitation, the v wave may become more prominent
(because the right atrium is receiving blood from both systemic venous return and the right ventricle). In constrictive pericarditis, the y descent becomes
prominent because the right ventricle rapidly fills in early diastole. In contrast, in pericardial tamponade, the right ventricle only fills during early systole, so
that only an x descent is observed. In both constrictive pericarditis and pericardial tamponade, mean jugular venous pressure is elevated.
