A patient presents to you with an irregularly irregular pulse of 120/minutes and a pulse deficit of 20. Which of the following would be the jugular venous pressure (JVP) finding?
Updated On: Jun 18, 2025
- Absent p wave
- Absent a wave
- Cannon a wave
- Raised JVP with normal waveform
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The patient described presents with an irregularly irregular pulse and a pulse deficit, which are classic indications of atrial fibrillation. In atrial fibrillation, the atria do not contract effectively, resulting in the absence of coordinated atrial activity. This disrupted contractile activity specifically affects the normal waveform of venous pulsations. The a wave in the jugular venous pulse corresponds to atrial contraction. Since atrial contraction is absent in atrial fibrillation, the a wave in the jugular venous pressure waveform is also absent.
| Finding | Explanation |
| Absent a wave | Due to atrial fibrillation causing lack of atrial contractions |
Thus, the correct option from the choices given is Absent a wave.
