RESUMEN
Late occurrence of atrioventricular nodal block is an extremely rare occurrence after radiofrequency catheter modification of the slow pathway and has yet to be reported after cryoablation. We report a case of late transient advanced second degree atrioventriuclar block after cryomodification of the slow pathway.
RESUMEN
J.V. is a 3(1/2)-year-old patient with left ventricular fascicular ventricular tachycardia that had been well controlled on verapamil for 3 years. He was taken for a transesophageal electrophysiology study prior to discontinuing medication in an attempt to induce his tachycardia. We report the use of transesophageal electrophysiology study as a noninvasive method to induce left ventricular fascicular ventricular tachycardia in a toddler.
