Abstract:
Transcatheter electrical ablation was performed in 5 patients, none of them showed clinical effectiveness for treatment of antiarrhythmic drugs, with recurrent sustained ventricular tachycardia (VT). The localization of ventricular ectopic focus mainly depended upon the results of pace mapping. Energy used for each transcatheter electrical ablation (TEA) was usually 150-250J and the total energy was 550J to 800J respectively for each patient. No recurrence of VT was ob-served in 4 cases during 19 to 41 (mean 26. 8) months of follow-up period, two of them without adminstration of drug. Sustained VT relapsed during the 4th months after ablation in one case, however, heart rate during VT was much slower than before. Our experience suggests that long-term effectiveness of TEA for treatment of drug-resist VT is inspiring.
