CLINICAL-RAISED JVP WAVEFORMS

SUMMARY

1. Large a waves: due to right ventricular or TV non-compliance. Occurs in tricuspid stensois, RVH.

2. Cannon a waves: dur to AV dissociation which occurs in complete heart block, VT or asynchronus pacing.

3. Rapid x descent: occurs in cardiac tamponade due to decreased RV compliance with loss of y-descent.

4. Large v waves: occurs in TR due to back-flow of blood into the already tense RA.

5. Rapid y descent: occurs in cardiac tamponade & constrictive pericarditis due to decreased RV compliance.
