Three days before presentation, a 7-year-old male German Shepherd dog had chewed a plastic ball, thereafter he vomited several times a day. Clinical examination, haematology, and clinical chemistry as well as thoracic radiographs showed radiopaque structures in the stomach. The dog was then anaesthetized in order to remove the foreign bodies using a rigid foreign body forceps under endoscopic control. It was observed that the dog was lethargic on following day. Clinical examination and electrocardiogram revealed respiratory bradyarrhythmia (43-60 beats/min). The echocardiographic examination revealed no abnormalities apart from the low heart rate. Due to persistent bradyarrhythmia, an atropine test was performed in order to distinguish arrhythmia disturbance due to a primary heart disease caused by vagus-induced bradyarrhythmia. After atropine administration, the heart rate increased within a few seconds to 135 beats/min. It was assumed that the procedure during the foreign body extraction caused the vagus-induced bradyarrhythmia. Seven days after endoscopy, the patient recovered and the heart rate was normal
