Fig. 2 One hour from a 24-hour ambulatory pH monitor tracing of the proximal and distal esophagus after a meal. Reading from the distal esophagus shows primarily pH >4 with only one transient decrease in pH, whereas recording from the proximal esophagus shows repeated drops in pH consistent with frequent episodes of acid exposure.
