Notice that there are no P waves, and that there are QRS-T wave forms of two types. The large QRSs with negative T waves are ventricular in origin.

After 24 hours, the ventricular tachycardia had resolved, but the atrial fibrillation was still present. The atrial fibrillation was successfully converted to sinus rhythm after several doses of quinidine sulphate had been given by nasogastric tube. <br><br>

Quinidine gluconate administered in intravenous boluses may also be used to treat atrial fibrillation of under two weeks duration in the horse.
