Jugular Venous Pressure (JVP)
- Ask patient to lie down on the examination table with head of bed elevated to 30-45 degrees
- Ask patient to look to the left as much as possible
- Landmark yourself between the two heads of the sternocleidomastoid.
- The JVP is an occludable, non-palpable, biphasic waveform or pulsation.
- If you cannot see the 2 heads of the SCM, have the patient push against your hand on the cheek
- Use ruler to assess JVP height to sternal angle
- Use ruler to measure it accurately
- Normal should be <5 cm above sternal angle
- Lookout for Kussmaul’s sign – JVP elevates with inspiration.
- This is a sign of severe pericarditis or RHF
- Lookout for beck’s triad – distended neck veins, low arterial BP, muffled heart sounds
- Press on liver to assess hepatojugular reflux (should return to normal within 10 seconds)
- Final Report: JVP is located and <5 cm above sternal angle
| JVP | Carotid |
|---|---|
| Occludable and bounces back after occlusion | Non-occludable |
| Non-palpable | Palpable |
| Biphasic | 1-1 Pulse to heartbeat |
| Decreases with elevated position and with inspiration | No change with position or inspiration |
| Increases with hepatojugular reflux | No change with hepatojugular reflux |
Pulsus paradoxus
- Check BP in both arms as usual and mention that you will continue to measure BP
- Listen for the first Korotkoff sound that appears then disappears with inspiration (recorded as SBP, as usual)
- Listen for when the sound no longer disappears with inspiration (a pressure in between SBP and DBP)
- Calculate the difference between these values; a difference of < 10 mmHg is normal – above this, is positive for pulsus paradoxus
- Then listen for the last sounds in series (DBP, as usual), deflate cuff more quickly as normal
- Final Report: The recorded drop in systemic blood pressure is <10mmHg, negative for pulsus paradoxus.
Carotid upstroke
- Rationale
- Carotid upstroke is a special test used to assess aortic stenosis & regurgitation
- Do if systolic murmurs are identified on auscultation
- While auscultating the heart, mention than you will place the pads of fingers over the carotid artery on patient’s neck
- As you listen for the murmur, there should be no delay between murmur onset (systole) and pulsation in the carotid
- If carotid pulse is delayed and relatively diminished, this is pulsus parvis et tardus (sign of aortic stenosis)
- If the carotid pulse is brisk, this may be a sign of aortic regurgitation
- If the carotid pulse is biphasic (2 pulses per cardiac cycle), this is called pulsus bisferiens and may be a sign of coexisting aortic stenosis and regurgitation.
