This 12 yr old 11 lb dog went to anesthesia for a dental. just after induction the patient experienced an arrhythmia and sever bradycardia. The procedure aborted. The patient had prolonged recovery. history of occasional cough,started seizures this year. 6 lead ecg heart rate 110 sinus arrhthmia. atropine response test revealed normal response.echocardiogram mild mitral and tricuspid regurg ,mild PI. No hypertension. no cardiac meds needed. The chest rads show possilby chronic airway disease or worse.

What was in your premed and
What was in your premed and induction drug Sherri? Did you try glyco before waking up?

What was the heart rate prior
What was the heart rate prior to sedtaion/GA? Although respiratory disease could have caused the increased vagal tone with the history of seizures would consider intra-cranial disease with increased intra-cranial pressure during the induction.
This was a referral for
This was a referral for cardiac work up.Unfortunately on the records they only note arrhythmia heard.There was no record sent with sedative ,induction agent,gas used. Corporate practice so see several doctors. I agree I am more inclined to be concerned about brain disease. Frustrating ! Thanks
