Characterization of esophageal contractility. Contraction pattern is not scored for ineffective swallows (DCI <450 mmHg·s·cm)

Contraction Vigor
Failed DCI <100 mmHg·s·cm
Weak DCI >100 mmHg·s·cm, but <450 mmHg·s·cm
Ineffective Failed or Weak
Normal DCI >450 mmHg·s·cm but <8,000 mmHg·s·cm
Hypercontractile DCI ≥8,000 mmHg·s·cm
Contraction Pattern
Premature DL <4.5 s
Fragmented Large break (>5 cm length) in the 20-mmHg isobaric contour with DCI >450 mmHg·s·cm
Intact Not achieving the above diagnostic criteria
Intrabolus Pressure Pattern (30 mmHg isobaric contour referenced to atmospheric)
Panesophageal pressurization Uniform pressurization of >30 mmHg extending from the UES to the EGJ
Compartmentalized Pressurization of >30 mmHg extending from the contractile
esophageal pressurization front to the EGJ
EGJ pressurization Pressurization restricted to zone between the LES and CD in conjunction with LES-CD separation
Normal No bolus pressurization >30 mmHg
