- Title
Retrograde slow‐wave activation: a missing link in gastric dysfunction?
- Authors
O'Grady, Greg; Gharibans, Armen; Calder, Stefan; Andrews, Chris
- Abstract
Dear Editors, We would like to congratulate Somarajan et al on their interesting article "The effect of chronic nausea on gastric slow-wave spatiotemporal dynamics in children".1 The authors applied body surface gastric mapping (5 × 5 electrodes and sophisticated signal processing) to study slow-wave abnormalities in children with chronic nausea. Spatial patterns from high-resolution electrogastrography correlate with severity of symptoms in patients with functional dyspepsia and gastroparesis. If retrograde activation is not accompanied by contractions (or incompletely so), they could still be clinically useful if they correlate with specific disease or symptom phenotypes.
