Defibrillation threshold (DFT) estimation with fewer VF inductions during ICD testing: Application of Upper Limit of Vulnerability (ULV) guided shock on T induction protocol in pediatrics

Abstract

(13-18 years)]. Patients with accessory pathways or previous ablations were excluded. Baseline values were determined in all patients. Additional medications (isoproterenol, atropine, or epinephrine) were used when supraventricular tachycardia (SVT) was not inducible at baseline. The longest AH jump was defined as the largest increase in AH interval with a 10 msec decrease in the premature stimulus. Results: At baseline, there were significant differences in dual AV node physiology between younger and older children.
