Multiple choice

The 'c'-waves in JVP are due to

  1. atrial contraction

  2. bulging of the tricuspid valve into the right atrium

  3. ventricular systole, when the tricuspid valve is closed

  4. none of these

B Correct answer
Explanation

The c-wave in the jugular venous pulse occurs due to bulging of the closed tricuspid valve into the right atrium during early ventricular systole (isovolumetric contraction). This creates a small rise in atrial pressure. It is distinct from the a-wave (atrial contraction) and v-wave (atrial filling against closed tricuspid valve).
