The occasion and clinical efficacy of radiofrequency ablation in the treatment of elderly patients with paroxysmal supraventricular tachycardia / 中国基层医药

ABSTRACT

Objective To explore the clinical pathological data of the elderly patients with paroxysmal supraventricular tachycardia(PSVT) and the timing of the radiofrequency ablation treatment for PSVT and its clinical efficacy.Methods The clinical pathological data of 45 elderly patients with PSVT for radiofrequency ablation were retrospectivly analyzed,and the information of cardiovascular and cerebrovascular diseases,the duration of PSVT and frequency of attacks,the reason of patients had to accept radiofrequency catheter ablation,the treatment effective of electrophysiological study and radiofrequency ablation were recorded.Results The duration and frequency of attacks with PSVT were positively related with pathogenesis in the elderly patients.Elderly PSVT patients with severe cardiovascular disease accounted for 28.89％.The first radiofrequency ablation treatment success rate was 100％ in this research and the recurrence rate was 4.4％.Conclusion It is recommended that elderly PSVT patients early access to the radiofrequency ablation.
