Plain-English summary
Two dogs were brought in for weakness caused by very fast heart rates, with one dog’s heart beating at 360 beats per minute and the other at 300 beats per minute. Tests showed they both had a type of heart rhythm problem called atrial flutter. The veterinarians performed a procedure called radiofrequency catheter ablation to correct the issue, successfully blocking the abnormal electrical signals in the heart. After the treatment, follow-up monitoring showed that both dogs no longer had arrhythmias and were feeling better.

Abstract
Two dogs were presented for episodic weakness caused by a very rapid supraventricular tachycardia with a ventricular rate of 360 bpm and 300 bpm, respectively. Electrocardiography showed narrow QRS complex tachycardia in both subjects, the first one with a fixed 2:1 atrioventricular block, and the second with variable degrees of atrioventricular block from 6:1 to 2:1. The electrophysiological studies revealed bidirectional and typical cavo-tricuspid isthmus-dependent atrial flutter, respectively. Radiofrequency catheter ablation was performed in both dogs and a bidirectional cavo-tricuspid isthmus block was successfully achieved. On follow-up, Holter monitoring confirmed resolution of the arrhythmias in both dogs.
