AF", 'role': 'user'}, {'content': "Answer: B \nExplanation: Giant v waves are seen in tricuspid regurgitation and VSD. v wave in a JVP represents atrial filling and occur during ventricular systole. In tricuspid regurgitation there is an accentuated v wave followed by a rapid y descend. In progressive TR, v wave merges with the c wave and the right atrial and juglar vein waveforms become ventricularised.
