Plain-English summary
A 1-year-and-7-month-old male crossbreed dog was brought in for fast heartbeats (supraventricular tachycardia) that caused him to feel tired and lose his appetite. Although a medication called sotalol helped reduce the episodes, it didn't completely solve the problem. The veterinary team used advanced mapping technology to find an abnormal electrical pathway in his heart and performed a procedure to destroy it with radiofrequency energy. After the treatment, the dog recovered well, and his owner reported no more symptoms. Follow-up tests showed that his heart was functioning normally without any recurrence of the fast heartbeats.

Abstract
A one-year-and-seven-month-old, 28 kg, male castrated crossbreed dog was presented for supraventricular tachycardia causing recurrent episodes of anorexia and lethargy. Sotalol (2.2 mg/kg q12 h) reduced the frequency of symptomatic episodes but did not provide full relief. Three-dimensional electroanatomical mapping was performed at the Ghent University Small Animal Teaching hospital using the CARTO 3. Right atrial activation mapping identified the earliest atrial activation right posteroseptal, near the tricuspid annulus. Fast retrograde ventriculoatrial conduction during tachycardia and extrastimulus testing confirmed the presence of a concealed right posteroseptal accessory pathway. Six radiofrequency catheter ablation applications were delivered, and tachycardia remained uninducible. The dog recovered well from the procedure. Sotalol was stopped three weeks later, and no more clinical signs were noted by the owner. Repeated 24-hour electrocardiography monitoring on day one and at one, three, and 12 months after the procedure showed no recurrence of tachycardia.
