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. c wave in jugular venous pulse tracing is due to carotid pulsation artefact. It is not visible to us during clinical examination. c wave in right atrial pressure tracing occurs during ventricular contraction when the tricuspid valves bulges upwards.
