Which of the following is a correctly matched correlation of jugular venous pulse?

Question

Quizplus · Accepted Answer

The correct match is loss of "a" wave: atrial fibrillation.
Pathological waveforms of JVP:
•Loss of "a" wave: A fib, atrial standstill
•Absent venous pulse: RHF/CHF, SVC obstruction, cardiac tamponade
•Giant "a" waves: contraction of atrium against increased resistance (RVH, PS, TS, pulmonary HTN)
•Cannon "a" waves: contraction of atrium against closed TV as in AV dissociation (AV dissociation, PVC)
•Systolic venous pulsation (c-v waves): regurgitation of blood into venous system with ventricular contraction as in TR (rapid "y")
•Sharp "y" descent: increased venous pressure as in constrictive pericarditis ("y">"x" phenomenon)
