SUMMARY
VALUES OF ELECTROCARDIOLOGY AND MANEUVERS IN RF ABLATION OF
ACCESSORY PATHWAY AT HUE CARDIOVASCULAR CENTRE
Introduction, method and materials: Accessory pathways is still the common substrate for

SVT and still a main subject in EP ablation practice in Vietnam. Retrospective study on 32
patients having EP ablation for AP in Hue Cardiovascular Centre.
Results: 19 males and 13 females with mean age of 41,9 ± 16,1 ranging from 17 years to 68
years. 24 with wpw syndrome and 8 concealed AP who all were women.
The success rate was 100% with low recurence rate and no complication. Fitzpatrick
algorithm was helpful for the localization of accessory atrioventricular connections using a
baseline electrocardiogram in wpw patients. Maneuvers have diagnostic value help reducing
mapping time and procedure time.
Conclusion: ECG algorithm and maneuvers have diagnostic values and contribute to the
success of accessory pathway ablation.
