Timing of Pharyngeal Swallow Events in Chagas’ Disease

Figures

Figure 1.
Figure 1. Mean of the timing of pharyngeal swallow events, in seconds, in patients with Chagas’ disease and control subjects after swallowing of 5 mL and 10 mL of liquid bolus. P > 0.05, controls vs. Chagas. OPP: onset of pharyngeal phase; OHM: onset of hyoid movement; UESO: upper esophageal sphincter opening; UESC: upper esophageal sphincter closing; EHM: end of hyoid movement.

Figure 2. Mean of the timing of pharyngeal swallow events, in seconds, in patients with Chagas’ disease and control subjects after swallowing of 5 mL and 10 mL of paste bolus. P > 0.05, controls vs. Chagas. OPP: onset of pharyngeal phase; OHM: onset of hyoid movement; UESO: upper esophageal sphincter opening; UESC: upper esophageal sphincter closing; EHM: end of hyoid movement.
