Plain-English summary
Ten dogs were studied after experiencing vomiting, which was triggered by either electrical stimulation in the stomach or balloon distention in the intestine. Before vomiting, the dogs showed a temporary abnormal pattern in their stomach's electrical activity, which returned to normal shortly after they vomited. The dogs recovered quickly after the vomiting episodes, suggesting that the abnormal electrical activity was a brief cause of their symptoms. This research helps to understand how stomach issues can lead to vomiting in dogs.

Abstract
BACKGROUND: The correlation between gastric myoelectrical activity (GMA) and gastrointestinal symptoms such as nausea and vomiting is poorly understood. The aim of this study was to assess the association of GMA with vomiting induced by retrograde gastric electrical stimulation or duodenal balloon distention. METHODS: Ten dogs were involved in this study. Vomiting was induced by retrograde gastric electrical stimulation in 6 dogs and by duodenal balloon distention in 4 dogs. Computerized spectral analysis and visual analysis were applied to detect the GMA change during various periods before and after vomiting. RESULTS: Gastric dysrhythmia preceded vomiting but was of brief duration. The major pattern of dysrhythmia immediately before vomiting was tachyarrhythmia and gastric slow wave was completely uncoupled before vomiting. Gastric dysrhythmia and slow wave uncoupling were also noticed immediately after vomiting but the dogs recovered quickly. The major pattern of dysrhythmia after vomiting was arrhythmia. GMA was normal during the periods other than 5 min before and during vomiting and 5 min after vomiting. CONCLUSIONS: Gastric dysrhythmia seems to be the cause of vomiting induced by retrograde gastric electrical stimulation or duodenal balloon distention. It is brief and characterized with tachyarrhythmia and uncoupling.
