Plain-English summary
An 11-year-old Labrador Retriever was brought in for surgery to remove a tumor in its mouth but was found to have a heart rhythm problem called ventricular tachycardia. To manage this issue during anesthesia, the veterinary team used a combination of lidocaine and remifentanil, which helped keep the dog's heart rate stable throughout the procedure. The dog did not experience any further arrhythmias during surgery, and the treatment was successful in controlling the heart condition.

Abstract
BACKGROUND: Ventricular tachycardia is an arrhythmia that, if not corrected, can lead to reduced ischemic stroke volume and cardiac output, resulting in low tissue perfusion. AIM: To describe a case of ventricular tachycardia suppression using lidocaine and remifentanil in a dog during the transanesthetic period. CASE DESCRIPTION: An 11-year-old Labrador Retriever dog with intraoral neoplasia was referred for hemimandibulectomy. Preanesthetic evaluation and complementary diagnostic tests revealed the presence of splenic neoplasia along with paroxysmal ventricular tachycardia. The preanesthetic medication was methadone, and the patient was induced into general anesthesia using propofol. During the transanesthetic period, anesthesia was maintained with sevoflurane and continuous infusion of lidocaine and remifentanil. Throughout the procedure, the patient remained in sinus tachycardia without any arrhythmic events. CONCLUSION: The arrhythmias on electrocardiogram during the transanesthetic period highlight the effective control of paroxysmal ventricular tachycardia through the use of lidocaine and remifentanil infusion.
