Model for Electrical Field Distribution in the Human Esophagus during Stimulation with Patch and Ring Electrodes

<table>The electrical field which exceeds a threshold of 20 V/m in the three anatomical layers is illustrated. The stimulation current range of the different stimulation electrodes is illustrated as the window between the sensory threshold (VAS 1) and the pain detection threshold (VAS 5).</table>
