Electrocardiographic findings in a dog with CTD during the 3d balloon inflation (22 mm balloon catheter). The trace reveals atrial (QRS complex similar to a sinus complex), ventricular (wide QRS complex followed by a large T wave) and junctional beats (QRS complex similar to a sinus complex and a negative P wave). The atrial beats are followed by ventricular beats, and junctional beats occurred when the balloon slipped distally against the tricuspid valve. Lead II tracing; Speed 25 mm/s; amplitude 10 mm/mV
