Fig. 4. High-resolution manometry representing a typical swallow characteristic of esophageal hypomotility disorders. (A) Absent peristalsis (100% of swallows with distal contractile integral [DCI] < 100 mmHg·sec·cm), (B) ineffective esophageal motility (over 70% of swallows with DCI ≤ 450 mmHg·sec·cm), and (C) fragmented peristalsis (at least 50% of swallows with ≥ 5 cm breaks in the peristaltic contour when contraction vigor is preserved) which is not maintained as a diagnostic category in Chicago classification version 4.0.
