- a-wave: Right atrial contraction
- Large a-wave: pulmonary hypertension
- Giant a-wave: CAVB
- No a-wave: atrial fibrillation.
- c: TV closure
- x-descent: Follows a-wave, as atrium relaxes.
- v-wave: Passive phase of atrial filling during ventricular systole
- y-descent: Brief decreases in jugular vein pressure after the Tricuspid valve opens (beginning of diastole)
