Effect of esophageal erosion on esophageal electrocardiogram.
We recorded an esophageal electrocardiogram in a rabbit before and after producing esophageal erosion. The erosion caused an increase in P wave and R wave height and inversion of the T wave. Esophageal erosion can thus cause false positive repolarization changes in the esophageal electrocardiogram.
