    Abstract:
    A new technique for the treatment of certain types of cardiac arrhythmias was used in a 3-year-old dog that was evaluated for incessant supraventricular tachycardia (220 to 280 beats/min), which had been refractory to several treatment regimens. The mechanism of supraventricular tachycardia was atrioventricular (AV) reentry, using a dorsoseptal accessory pathway (AP) for retrograde ventriculoatrial conduction (concealed AP). With the dog under general anesthesia and with fluoroscopic monitoring, electrode catheters were introduced into the heart via peripheral vessels. Electrical recordings allowed localization of the accessory AV pathway. Programmed electrical stimulation was used to verify the function of the abnormal AV connection. At the atrial insertion site of the AP, 2 applications of radiofrequency current (45 V, 21.6 W) were delivered to the dorsoseptal right atrium (near the coronary sinus ostium), which eliminated AP conduction and AV reentrant tachycardia. The dog has remained free of tachycardia and has not required medication during more than 1 year of follow-up.
