摘要
Abstract
AIM: To assess the clinical efficacy of electro-anatomically guided mapping and radiofrequency ablation under CARTO system for frequent premature ventricularcontraction. METHODS: The CARTO electro-anatomical mapping system displays real time three dimensional chamber structure with electrical information related to signal mplitude and activation time. 22 patients with Drug refractory and frequent premature ventricular contractions were ablated under CARTO system. By preoperative and postoperative SF-36, the generally health, physical function and conduct scoring among patients after procedure were observed. RESULTS:Frequent premature ventricular contractions were successfully ablated in all 22 patients with mean 2. 6± 1.2 radiofrequency applications under CARTO system. 19/22 frequent premature ventricular contractions occurred in right ventricle, and 3/22 in left ventricule. After ab-lation, the premature ventricular contractions declined from (17932 + 3816) beats/24 h to (13 ±6) beats/24 h, and patients symptoms almost disappeared. No recurrent case was found during following observation. The patient overall quality of life improved markedly. CONCLUSION: The CARTO electro-anatomical mapping system, referred to the electro physiologic data, may be applied in guiding the radiofrequency ablation of drug-refractory and frequent premature ventricular contractions in those patients who have no organic heart disease for its highly efficacy, safety and accurate orientation, and could significantly improve patient quality of life.关键词
