Multiple Rapid Swallows (MRS) Complements Single-Swallow (SS) Analysis for High-Resolution Esophageal Manometry (HREM).

MRS IRP correlated with SS IRP, and post-MRS DCI correlated with SS DCI. Patients with defined CC disorders have abnormalities on MRS. There were MRS abnormalities in some patients with normal SS studies, most notably suggesting impaired LES relaxation and/or spastic esophageal motility. MRS may complement the baseline SS study analysis.
