Jugular venous pressure
From IDWiki
- normal JVP is <9cm above RA (<4 cm above sternal angle)
Abnormalities of the Venous Waveforms
| Waveform | Cardiac Condition |
|---|---|
| Absent a wave | Atrial fibrillation, sinus tachycardia |
| Flutter waves | Atrial flutter |
| Prominent a waves | First-degree atrioventricular block |
| Large a waves | Tricuspid stenosis, right atrial myxoma, pulmonary hypertension, pulmonic stenosis |
| Cannon a waves | Atrioventricular dissociation, ventricular tachycardia |
| Absent x descent | Tricuspid regurgitation |
| Prominent x descent | Conditions causing enlarged a waves |
| Large cv waves | Tricuspid regurgitation, constrictive percarditis |
| Slow y descent | Tricuspid stenosis, right atrial myxoma |
| Rapid y descent | Constrictive pericarditis, severe right heart failure, tricuspid regurgitation, atrial septal defect |
| Absent y descent | Cardiac tamponade |
