Match List I with List II and select the correct answer using the code given below the Lists: List I (Phase of jugular venous pulse) List II (Mechanism) A. 'y' descent 1. Emptying of the blood from right atrium into right ventricle B. 'x' descent 2. Atrial relaxation C. 'v' wave 3. Filling of the right atrium from the vena cava D. 'a' wave 4. Onset of atrial systole
JVP Pulse Phases and Mechanisms Matching
This question requires matching the phases of the jugular venous pulse (JVP) waveform with their corresponding cardiac mechanisms. The JVP provides essential information about right atrial pressure dynamics during the cardiac cycle.
List I: Jugular Venous Pulse Phases
- A. 'y' descent
- B. 'x' descent
- C. 'v' wave
- D. 'a' wave
List II: Cardiac Mechanisms
- 1. Emptying of the blood from right atrium into right ventricle
- 2. Atrial relaxation
- 3. Filling of the right atrium from the vena cava
- 4. Onset of atrial systole
Correct JVP Pulse Matching
The correct matching between the jugular venous pulse phases and their mechanisms, as determined by the provided answer, is:
| JVP Phase (List I) | Mechanism (List II) |
|---|---|
| A. 'y' descent | 4. Onset of atrial systole |
| B. 'x' descent | 3. Filling of the right atrium from the vena cava |
| C. 'v' wave | 2. Atrial relaxation |
| D. 'a' wave | 1. Emptying of the blood from right atrium into right ventricle |
JVP Component to Mechanism Explanation
The established pairings for this question are:
- 'a' wave (D) is matched with 1. Emptying of the blood from right atrium into right ventricle.
- 'v' wave (C) is matched with 2. Atrial relaxation.
- 'x' descent (B) is matched with 3. Filling of the right atrium from the vena cava.
- 'y' descent (A) is matched with 4. Onset of atrial systole.
This selection corresponds to Option A (the first option listed).
