y descent in the jugular venous pulse – Medicine MCQ – CVS – Answer

y descent in the jugular venous pulse represents – Correct answer: b) Passive atrial emptying in early diastole when the ventricle relaxes.

Atrial contraction produces the a wave, occurring just before the ventricular systole. a wave is naturally absent in atrial fibrillation. Atrial relaxation and displacement of the tricuspid valve ring towards the apex causes the x descent. wave in jugular venous pulse tracing is due to carotid pulsation artefact. It is not visible to us during clinical examination. wave in right atrial pressure tracing occurs during ventricular contraction when the tricuspid valves bulges upwards.
