Figure 2

A) Repetitive, antegrade contractions (RACs) from a patient with normal motility on high-resolution manometry (HRM). RACs were the most commonly observed contractile pattern in asymptomatic controls.(10, 11) B) Contractility without RAC or repetitive, retrograde contractions in a patients with a HRM demonstrating EGJ outflow obstruction with a peristaltic pattern of ineffective esophageal motility. C) Absent contractility in a patient with type I achalasia on HRM. D). Repetitive, retrograde contractions (RRCs) in a patient with type III achalasia on HRM.
