Secondary contractions were observed when there was an esophageal contraction within 20 s after water, HCl, or air infusion. Primary peristalsis was elicited by ten swallows of a 5-mL bolus of water and secondary peristalsis was elicited by intra-esophageal infusion of 5, 10, and 15 mL water, 0.1 N hydrochloric acid and air.
