Abstract:
Objective To study the clinical characterics of 139 patients with wide QRS complex tachycardia.Methods Retrospective analysis was performed on 139 patients with QRS wave tachycardia treated by radiofrequency ablation at TEDA International Cardiovascular Hospital.The patients were divided into supra-ventricular tachycardia with intra-ventricular aberrany group (group A,n =84) and ventricular tachycardia (group B,n =55).The clinical data,electrocardiogram (ECG) and echocardiographic features between the two groups were compared.Results There was no statistical significance between the two groups in terms of gender,height,weight and ventricular rate (P ＞ 0.05).The difference in the course of disease,blood pressure,age,QRS duration,left ventricular diameter by echocardiography and ejection fraction was statistically significant (P ＜ 0.05).Radiofrequency ablation result showed that 81 (96.4％) cases were successful in group A,and 37 (67.3％) cases were successful in group B.The difference in the success rate was statistically significant (P ＜0.05).After 1 year of follow-up,4 (2.9％) cases in group A were recurred,13 (23.6％) cases in group B were recurred.The difference in the recurrence rate was statistically significant.Conclusion The wide QRS wave tachycardia is often accompanied with left ventricular diameter enlargement and left ventricular ejection fraction reduction,The success rate of radiofrequency ablation is low,and the recurrence rate is high when diagnosis is ventricular tachycardia.
