Figure 1 Sinus arrhythmia maneuver. (Upper panels) Esophageal and esophagogastric junction (EGJ) pressure topography is shown during six 5-s inhalations (I). Inspiratory diaphragm lowering was then determined (A). The analysis landmarks are presented in the upper right panel (II). In this case, the e-sleeve extended approximately 6 cm across the EGJ. (Lower panel) (III) Esophageal and EGJ pressure tracings during sinus arrhythmia maneuver (SAM) where inspiratory peak pressures were measured (B) relative to expiratory pressure.
