- A-V dissociation (complete heart block, V.T.) (cannon A waves) RA contracts against the closed TV
C Wave
-What is going on when you see this wave?
Backward push by closure of TV during isovolumetric systole and by impact of carotid artery adjacent to the JV
X wave- X slope
- What is going on when you see this wave?
- Steep X descent seen in?
- Passive atrial filling and atrial relaxation
- Blood flows into the RA from the cava and closure of TV
- Steep X descent in cardiac tamponade and constrictive pericariditis
V wave
- What is going on when you see this wave?
- Prominent V wave in?
- Atrial filling
- Increasing volume and pressure in RA when TV closed
- Prominent V wave in TR and pulmonary hypertension
Y slope or Y descent
- What is going on when you see this wave? - Deep Y descent in? - A slow Y descent suggests?
- Open TV and rapid RV filling in RV diastole
- Deep Y descent in severe TR
- A slow Y descent suggests obstruction to RV filling (i.e. TS or RA myxoma)
Increased JVP in?
- SVC obstruction
- Severe heart failure
- Constrictive pericariditis, cardiac tamponade, RV infarction
- Restrictive cardiomyopathy
Positive HJR in?
- Poorly compliant RV, RV failure

Cardiac cycle
-Systole?
Ventricular contraction, ejection
Cardiac cycle

Ventricular relaxation, filling
