Abstract：Objective To analyze the effect of high-power radiofrequency ablation in the treatment of paroxysmal atrial fibrillation patients on the stress factors and the ablation time.Methods 60 patients with paroxysmal atrial fibrillation treated in our hospital from January 2022 to December 2023 were selected as study subjects and divided into two groups by random number table,with 30 patients in each group.The control group received conventional radiofrequency ablation at 40 W,while the observation group underwent high-power radiofrequency ablation at 50 W.Operation time and ablation time,levels of stress factors before and after treatment,levels of cardiac ultrasound-related indicators,and follow-up outcomes 6 months after treatment were compared between the groups.Results The operation time and ablation time in the observation group were shorter than those in the control group(t=3.007,P=0.004;t=5.821,P<0.001,respectively).Before treatment,there were no significant differences in stress factor levels between the groups(P>0.05).After treatment the levels of all stress factors in the observation group were lower than those of the control group(P<0.05).The levels of cardiac ultrasound-related indicators between the groups before treatment were insignificant(P>0.05).After treatment LAFI and LAEF of the observation group were significantly higher than those in the control group(t=3.367,P<0.001;t=4.812,P<0.001,respectively),and LAVmax and LAVmin were lower than those of the control group(t=2.418,P=0.019;t=4.405,P<0.001,respectively).Six months after treatment,there were no significant differences in disease recurrence,atrial arrhythmia or sinus rhythm(P>0.05).Conclusion The application of high-power radiofrequency ablation in the treatment of patients with paroxysmal atrial fibrillation can effectively shorten the operation time and ablation time,reduce the level of patient stress factors,and improve the level of cardiac ultrasound-related indicators of patients,which has high clinical treatment reference value.
